1. Introduction

System 500 is used to receive signals from GPS satellites which are then processed to obtain a position on the earth’s surface.

It can be used in many applications, the main ones being Land Survey, Stakeout and Hydrographic Survey.

The main components of System 500 are the GPS Antenna and GPS Receiver. Ancilliary components are the Terminal, Batteries, PC Cards and cables.

SKI-Pro, a PC based software is also used in conjunction with the hardware listed above for post-processing GPS data and for downloading coordinates

recorded in the field. Instructions for System 500 - main hardware components using SKI-Pro can be found in the

accompanying printed guides and online help.

Technical Reference Manual-4.0.0en

1. Introduction

1.1 The GPS Antenna

There are several System 500 GPS Antennas available. These are:

•AT501 Single Frequency Antenna.

•AT502 Dual Frequency Antenna.

•AT503 Dual Frequency Choke Ring Antenna.

•AT504 JPL Design Dual Frequency Choke Ring Antenna.

•Single Frequency Choke Ring Antenna.

The GPS Antenna is selected for use based upon the application. The vast majority of applications will require the AT501 or AT502 Antenna.

The AT501 is a L1 single frequency antenna. Use it with the SR510 Receiver. The AT502 is a dual frequency antenna. Use it with the SR520 or SR530 Receiver.

The Choke Ring Antennas are designed for use where the utmost precision is required. Typical applications include Static Surveys of long baselines, Tectonic Plate monitoring, Reference Stations, etc.

Use the AT503 and AT504 with the SR520 or SR530 Receiver. Use the Single Frequency Choke Ring with the SR510 Receiver.

Also available is a combined GPS/

AT502 Antenna

1.2 The GPS Receiver

The GPS Receiver is the instrument that processes the GPS signals received by the GPS Antenna.

There are six different models of GPS receiver in System 500. The model number is printed on the PC card lid.

See the detailed descriptions of each of these receivers given down below.

SR510 - Tracks the L1 C/A code and uses it to reconstruct the carrier phase. Data can be stored for postprocessing in SKI-Pro. Baselines can be calculated with a precision of up to about 5-10mm +2ppm.

With a radio modem attached the receiver can be used for real-time measurements accepting RTCM code corrections. Coordinates can be calculated with a precision of up to about 0.5m.

SR520 - Tracks the L1 C/A code and L2 P-code to reconstruct the carrier phase. When Anti-Spoofing (A-S) is activated, the receiver switches to a patented P-code aided tracking technique that provides full L2 carrier measurements and L2 pseudoranges. Data can be stored for post-processing. Baselines can be calculated with a precision of up to about 3-10mm +1ppm.

With a radio modem attached the receiver can be used for real-time measurements accepting RTCM code corrections. Coordinates can be calculated with a precision of up to about 0.5m.

SR530 - Tracks the L1 C/A code and L2 P-code to reconstruct the carrier phase. When Anti-Spoofing (A-S) is activated, the receiver switches to a patented P-code aided tracking technique that provides full L2 carrier

measurements and L2 pseudoranges. A radio modem attaches and the receiver can be used for RTK operations. Coordinates can be calculated with a precision of up to about 1cm

Data can also be stored for postprocessing. Baselines can be calculated with a precision of up to about 3-10mm +1ppm.

System 500 GPS Receivers can be operated with or without the TR500 Terminal (see section 1.3). The TR500 is used for field data acquisition and for configuring the receiver.

Details of using the Receiver without a Terminal are given in Chapter 3.

1. Introduction

MC500 - A ruggedized version of the SR530 designed specifically for Machine Control. Can also be utilised as a dedicated GPS Reference Station. Please refer to Appendix I for specific details.

RS500 - A dedicated GPS Reference Sation receiver designed for permanent installation. Please refer to Appendix J for specific details.

GS50 - This receiver has been specifically designed for GIS applications. Please refer to Appendix K for more information that is specific to the GS50 and the corresponding PCsoftware GIS DataPRO.

1. Introduction

Technical Reference Manual-4.0.0en

1.3 The TR500 Terminal

The TR500 Terminal provides a full user interface to all System 500 GPS Receivers.

It can be used to set parameters in the receiver and to steer the GPS measurement operation.

The TR500 can be used to set and store parameters in one GPS receiver and then removed and used to set parameters in another System 500 receiver. The receiver can then be used in the field without the TR500 attached. Note that whilst this is possible when measuring in any mode, for a Reference or Rover, it is recommended that the Receiver only be used without a TR500 at Reference stations or with Static/Rapid Static Rovers.

The TR500 is connected either	TR500 mounted on the Receiver			TR500 connected using the cable
directly to the receiver or via a cable.
Data input is via a fully alphanumeric
QWERTY keyboard and an LCD
display of 32 x 12 characters which
may be illuminated.
Technical Reference Manual-4.0.0en		15		1. Introduction

1.4 Data Storage

Data is stored on either an Internal Memory or PC Card. The PC Card is the preferred data storage medium. The Internal Memory is an option.

The PC Card is inserted into the slot on the front of the GPS Receiver. PC Cards are available from Leica with varying capacities. Note that whilst other PC Cards may be used, Leica recommend Leica PC cards only and cannot be held responsible for data loss or any other error that may occur whilst using a non-Leica card.

To insert the PC Card in the GPS Receiver, open the card slot door, with the Leica Logo uppermost and facing you, slide the card into the slot firmly until it clicks into position. Press the eject button at the side of the card to remove it.

The Internal Memory is available in
8MB or 16MB capacities and resides
in the Receiver. When data has to be
downloaded to SKI-Pro, connection is
made between port 2 on the Receiver
and a serial port on the PC.
The memory device is checked
before starting a survey. If it is more
than 80% full, an information mes-
sage appears.
	Inserting the PC Card
Follow the care instructions shown on
the rear of the card. Keep the card
dry, only use within the specified
temperature range, do not bend the
card and protect it from direct shock.
Failure to follow these instructions
could result in data loss and/or
permanent damage to the card.
The card can become very hot during
use. Avoid touching the metal parts of
the card after prolonged use.

1. Introduction

Technical Reference Manual-4.0.0en

PC Card versus Internal Memory

The PC Card is the preferred data storage medium as it has the following advantages over internal memory:

•Faster download times. A PC Card download using a PC Card Reader or PCMCIA port is virtually instantaneous. Internal memory has to download through a serial connection and can take time.

•Flexibility / no downtime of GPS Receiver. A PC Card can be removed from a receiver when it is full and replaced with a spare. The Receiver does not

have to be taken back to the office for downloading.

Using an Internal Memory means however that the data has less chance of being misplaced or lost. This can happen when multiple PC Cards are used for the same project.

If you are not sure about which type of memory to use, try using a PC card but don’t remove it from the Receiver. You can still download as if it were Internal Memory through any port.

1.5 Batteries/Power Supply

Connecting a GEB121 Battery

Removing a GEB121 Battery

System 500 will normally be powered by two GEB121 camcorder type batteries. which plug into the underside of the GPS receiver.

Two batteries, fully charged, will power the SR510 and TR500 for about 7.5 hours continuously and the SR520/530 for about 6 hours continuously.

Operating times will be shorter when working in cold weather and when a radio modem is connected.

Plug in and remove the GEB121 batteries as shown opposite.

System 500 can also be powered by the GEB71 7Ah battery or any 12V DC power supply via either power port, on the front face of the receiver using an appropriate cable.

With the Receiver upside down and the Leica logo on the battery facing you, locate one end into the battery bay. Press the opposite end of the battery down until it audibly clicks into place.

Pull and hold the battery catch. Withdraw the battery with the other hand.

The battery contains toxic material and must be disposed of in an environmentally friendly manner. Do not dispose of the battery in normal household or office waste.

The Next Steps

If the Receiver has been pre-pro- grammed and the TR500 is not being used, further guidance is available in Chapter 3.

If the Receiver has been pre-pro- grammed and the TR500 is being used, further guidance is available in Chapter 7.

If the Receiver requires programming with the TR500, further guidance is available in Chapter 5.

When Using the GAD31 adapter and GRT144 carrier,

ensure that the Antenna and GAD31 assembly slide down the full length of the GRT144 stub. An incorrectly mounted Antenna will have a direct effect on your results.

In wet conditions the Receiver can be placed in the

transport case during use for extra protection. Try to shut the case as completely as possible.

If the Receiver is left in the case during use in tempera-

tures exceeding 25°C, the lid should be left open. Refer to Appendix A for operating and storage temperatures.

Use an external battery such as GEB71 to extend the

operating time past 6 hours.
