Safety Information

Before you use your Trimble® SPS GPS receiver, make sure that you have read and understood all safety requirements.

Regulations and safety

The receivers contain an internal radio-modem and can send signals through Bluetooth® wireless technology (SPSx50 Modular GPS receiver and the SPSx80 Smart GPS antenna only) or through an external data communications radio. Regulations regarding the use of the radio-modems vary greatly from country to country. In some countries, the unit can be used without obtaining an end-user license. Other countries require end-user licensing. For licensing information, consult your local Trimble dealer.

Before operating an SPSx50 Modular GPS receiver or SPSx80 Smart GPS antenna, determine if authorization or a license to operate the unit is required in your country. It is the responsibility of the end user to obtain an operator’s permit or license for the receiver for the location or country of use.

For FCC regulations, see Notices, page iii.

Type approval

Type approval, or acceptance, covers technical parameters of the equipment related to emissions that can cause interference. Type approval is granted to the manufacturer of the transmission equipment, independent from the operation or licensing of the units. Some countries have unique technical requirements for operation in particular radio-modem frequency bands. To comply with those requirements, Trimble may have modified your equipment to be granted Type approval. Unauthorized modification of the units voids the Type approval, the warranty, and the operational license of the equipment.

Exposure to radio frequency radiation

For 450 MHz radio

Safety. Exposure to RF energy is an important safety consideration. The FCC has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment as a result of its actions in General Docket 79-144 on March 13, 1986.

Proper use of this radio modem results in exposure below government limits. The following precautions are recommended:

•DO NOT operate the transmitter when someone is 20 cm (7.8 inches) of the antenna.

•DO NOT operate the transmitter unless all RF connectors are secure and any open connectors are properly terminated.

SPSx50 Modular GPS Receiver User Guide v

Safety Information

•DO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere.

•All equipment must be properly grounded according to Trimble installation instructions for safe operation.

•All equipment should be serviced only by a qualified technician.

For license-free 900 MHz radio

C	CAUTION – For your own safety, and in terms of the RF Exposure requirements of the
	FCC, always observe the precautions listed here.

•Always maintain a minimum separation distance of 20 cm (7.8 inches) between yourself and the radiating antenna on the SPSx50 radio-modem.

•Do not co-locate the antenna with any other transmitting device.

For Bluetooth radio

The radiated output power of the internal Bluetooth wireless radio is far below the FCC radio frequency exposure limits. Nevertheless, the wireless radio shall be used in such a manner that the Trimble receiver is 20 cm or further from the human body. The internal wireless radio operates within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community. Trimble therefore believes the internal wireless radio is safe for use by consumers. The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices such as mobile phones. However, the use of wireless radios may be restricted in some situations or environments, such as on aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before turning on the wireless radio.

Installing antennas

C	CAUTION – For your own safety, and in terms of the RF Exposure requirements of the
	FCC, always observe these precautions:
	– Always maintain a minimum separation distance of 20 cm (7.8 inches) between yourself
	and the radiating antenna.
	– Do not co-locate the antenna with any other transmitting device.
	This device has been designed to operate with the antennas listed below, and having a
	maximum gain of 5 dBi. Antennas not included in this list, or having a gain greater
	than 5 dBi, are strictly prohibited for use with this device. The required antenna
	impedance is 50 ohms.
	The antennas to be used with the 450 MHz radio are 0 dBi and 5 dBi whip antennas.
	The antennas to be used with the 900 MHz radio are 0 dBi, 3 dBi, and 5 dBi whip
	antennas.
	To reduce potential radio interference to other users, the antenna type and its gain
	should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
	more than that permitted for successful communication.

Use and care

This product is designed to withstand the rough treatment and tough environment that typically occurs in construction applications. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.

C	CAUTION – Operating or storing the receiver outside the specified temperature range can
	damage it. For more information, see Chapter 10, Specifications.

COCOM limits

The U.S. Department of Commerce requires that all exportable GPS products contain performance limitations so that they cannot be used in a manner that could threaten the security of the United States. The following limitations are implemented on this product:

•Immediate access to satellite measurements and navigation results is disabled when the receiver velocity is computed to be greater than 1000 knots, or its altitude is computed to be above 18 000 meters. The receiver GPS subsystem resets until the COCOM situation clears. As a result, all logging and stream configurations stop until the GPS subsystem is cleared.

QOperating the receiver with a Trimble controller

The SPSx50 GPS receiver uses an internal rechargeable Lithium-ion battery, which can be replaced only at an Authorized Trimble Service Center.

The receiver can also be powered by an external power source that is connected to the Lemo or modem port.

The operational time provided by the internal battery depends on the type of measurement and operating conditions. Typically, the internal battery provides 10 hours operation as a base station and 12 hours as a rover during measurement operations using the internal radio.

Note – All battery operation tests are carried out with new, fully charged batteries at room temperature and full receiver configuration operational. Older batteries, at temperatures significantly higher or lower than room temperature, will have a reduced performance. Receivers operating with reduced configuration will have a higher performance.

3Batteries and Power

External power

The GPS receiver uses an external power source in preference to its internal batteries. If the receiver is not connected to an external power source, or if the external power supply fails, the internal batteries are used.

While carrying out static measurements for postprocessed computations using the internal memory, if no external power is supplied and the internal battery is drained, the receiver shuts down. No data is lost and when power is restored, the receiver restarts in the same status as it was when power was lost.

Battery safety

	The receiver is powered by a rechargable internal Lithium-ion battery. Charge and use
	the battery only in strict accordance with the instructions below.
C
	WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
	can cause an explosion or fire, and can result in personal injury and/or property damage.
	To prevent injury or damage:
	– Do not use or charge the battery if it appears to be damaged. Signs of damage include,
	but are not limited to, discoloration, warping, and leaking battery fluid.
	– Do not expose the battery to fire, high temperature, or direct sunlight.
	– Do not immerse the battery in water.
	– Do not use or store the battery inside a vehicle during hot weather.
	– Do not drop or puncture the battery.
	– Do not open the battery or short-circuit its contacts.
C
	WARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be
	leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or
	property damage.
	To prevent injury or damage:
	– If the battery leaks, avoid contact with the battery fluid.
	– If battery fluid gets into your eyes, immediately rinse your eyes with clean water and
	seek medical attention. Do not rub your eyes!
	– If battery fluid gets onto your skin or clothing, immediately use clean water to wash off
	the battery fluid.

Battery performance

To optimize battery performance and extend battery life:

•Fully charge all new batteries before use.

•Batteries perform best when they are not used at extreme temperatures. The receiver is designed to operate at –40 °C to +65 °C (–40 °F to +149 °F). However, operation at temperatures of less than 0 °C (32 °F) can cause a rapid drop in battery life.

•Do not allow a battery that is in storage to discharge to below 5 V.

Batteries and Power 3

Charging the Lithium-ion battery

	The rechargeable Lithium-ion battery is supplied partially charged. Charge the battery
	completely before using it for the first time. If the battery has been stored for longer
	than three months, charge it before use.
	The internal battery charges fully in 8 hours when connected to a suitable power
	source.
C
	WARNING – Charge and use the rechargeable Lithium-ion battery only in strict
	accordance with the instructions. Charging or using the battery in unauthorized
	equipment can cause an explosion or fire, and can result in personal injury and/or
	equipment damage.
	To prevent injury or damage:
	– Do not charge or use the battery if it appears to be damaged or leaking.
	– Charge the Lithium-ion battery only with a Trimble product that is specified to charge it.
	Be sure to follow all instructions that are provided with the battery charger.
	– Discontinue charging a battery that gives off extreme heat or a burning odor.
	– Use the battery only in Trimble equipment that is specified to use it.
	– Use the battery only for its intended use and according to the instructions in the product
	documentation.

Storing the Lithium-ion battery

If you must store a Lithium-ion battery for long periods, make sure that it is fully charged before it is stored, and that you charge it at least once every three months while it is stored.

Do not allow a battery that is in storage to discharge to below 5 V. A battery that reaches deep discharge level (5 V or less) cannot be recharged and must be replaced. (To protect a battery that is in use from deep discharge, the receiver switches power sources or stops drawing power when the battery pack discharges to 5.9 V.)

All batteries discharge over time when not in use, and they discharge faster in colder temperatures. Do not store the receiver at temperatures outside the range –40 °C to +70 °C (–40 °F to +158 °F).

The SPSx50 receiver has an internal Lithium-ion battery. The internal battery will only charge from an external power source that delivers more than 15 volts, for example, an AC power adaptor. The receiver is supplied with a mains power supply unit that recharges the battery inside the receiver when it is connected through the adaptor to the modem port or the Lemo port. When you use the receiver on large projects, from a permanent or semi-permanent base station location in a site trailer, Trimble recommends that you use this power supply at all times to keep the internal battery charged. This provides an uninterrupted power supply and will keep the site operational for more than 10 hours after a power failure.

Keep all batteries on continuous charge when not in use. You can keep batteries on charge indefinitely without damage to the receiver or to the batteries.

Removing the rechargeable Lithium-ion battery

The internal Lithium-ion battery should be removed only at an authorized Trimble Service Center. If the battery is removed at an unauthorized service center, the remaining warranty on the product will be void.

Operating the receiver with a Trimble controller

You can operate an SPS GPS receiver with any Trimble controller, for example, a TSC2 or TCU controller, that is running the SCS900 software. Typically, the receiver and the controller operate from their own individual power sources. The receiver and controller can communicate through Bluetooth wireless technology and can be connected without a cable. However, if a cable is required, the following information indicates which cable to use with which controller:

Controller	Cable	Controller connector	Receiver connector
TSC2	P/N 18532	DSub9	DSub9

GPS Real-Time Kinematic (RTK) operation provides centimeter-level accuracy by eliminating errors that are present in the GPS system. For all RTK operations, you require both a base station and a rover receiver.

This chapter introduces the concepts of base station and rover operation, provides information to help you identify good setup locations, describes best practices for setting up the equipment, and outlines the precautions that you need to take to protect the equipment.

Note – This chapter provides setup information for all the receivers in the SPS GPS receiver family.

4Setup Guidelines

Base station operation guidelines

A base station consists of a receiver that is placed at a known (and fixed) position. The receiver tracks the same satellites that are being tracked by the rover receiver, at the same time that the rover is tracking them. Errors in the GPS system are monitored at the fixed (and known) base station, and a series of position corrections are computed. The corrections are sent through a radio link to the rover receiver, where they are used to correct the real time positions of the rover.

Base station components

The base station has the following components:

•GPS receiver

•GPS antenna

•Base station radio

•Power supply

GPS receiver and GPS antenna

The base station GPS receiver can be one of following types:

•A Smart GPS antenna, such as the SPSx80, which incorporates a GPS receiver, GPS antenna, power supply, and base station radio into a single compact unit. A Smart GPS antenna can be rapidly set up on a tripod, fixed height tripod, or T-Bar anywhere that is convenient on the jobsite.

•A Modular GPS receiver, such as the SPSx50, which incorporates a GPS receiver, power supply, and base station radio in a single unit. The GPS antenna (and, optionally, the base station radio antenna) is separate from the receiver. Because the GPS antenna is separate, you can use the following optimized components:

–a geodetic antenna with large ground plane, to eliminate multipath (the major source of GPS errors) at the base station

–a high gain or directional radio antenna, to increase broadcast range and to provide maximum coverage

You can also place a modular GPS receiver in an easily accessible and secure location, safe from theft and the weather, while the antennas are placed high on a tower or building, clear of obstructions and able to deliver maximum performance.

You can use either type of receiver in a permanent, semi-permanent, or daily quick setup configuration. If semi-permanent or permanent operation is required, however, the modular receiver delivers significant advantages.
