GPS 114 receiver

Overview 1

As part of a Precision Agriculture System, the receiver provides submeter (less than 3.28 ft) static HRMS accuracy. To achieve this, the receiver uses NMEA-0183 and TSIP (Trimble Standard Interface Protocol) messages. The dynamic pass-to-pass accuracy is better than the static accuracy . You can also use a 1 PPS (pulse per second) strobe signal to synchronize time for logging event markers when you are using external instruments.

You can use the receiver with a variety of farming equipment, including yield monitors, parallel swathing guidance systems, variable-rate planters, spray application controllers, and portable field computers for field mapping and soil sampling.

1.2.1

GPS 114 Receiver User Guide

Overview 1

• 1 PPS output To synchronize timing between external instruments and the

receiver’s internal clock, the connection port outputs a strobe signal at 1 PPS (pulse per second). To output this signal, the receiver must be tracking satellites and computing GPS positions.

• J1939 (CAN) serial bus Both serial ports support the J1939 CAN (Controller Area

Network) bus protocol. This protocol standardizes the way multiple microprocessor-based electronic control units (ECUs) communicate with each other over the same pair of wires. It is used in off-highway machines, such as those used in agriculture, construction, and forestry. For more information, visit the SAE International website (www.sae.org/servlets/index)

1.3

Differential GPS (DGPS)

The AgGPS 114 receiver uses DGPS to achieve high accuracy. One receiver (this is called the reference or base station) is located at a known point. This receiver is used to determine GPS signal measurement errors. One or more mobile receivers (called rovers) collect data at unknown locations, while remaining within range of the reference station. The reference station broadcasts correction values, which are applied to the receiver positions. In this way, errors common to the reference and rover receivers are corrected.

For more information about DGPS and the different DGPS signals available, visit the Trimble website (www.trimble.com/gps/dgps.html).

GPS 1 14 Receiver User Guide 9

1 Overview

1.3.1

Sources of GPS error

Autonomous (GPS only) horizontal accuracy for Trimble AgGPS receivers ranges from approximately 3–9 meters (about 10–30 ft).

The errors that cause this reduced accuracy are produced mainly by atmospheric conditions, multipath, (GPS signals bouncing off objects before reaching the antenna), and electronic or GPS frequency noise interference.

DGPS removes most of the errors caused by atmospheric conditions, errors which are further minimized by the advanced design of the

AgGPS 114 receiver. For more information, see the section on Error Correction on the Trimble website at

www.trimble.com/gps/errors1.html

Note – In some agricultural applications that do not require high accuracy, a maximum PDOP of 12 or more can be used.

> 6 Signal-to-Noise ratio (SNR) is a measure of the satellite

signal strength against electrical background noise. A high SNR gives better accuracy.

> 7.5 Satellite that are low on the horizon typically produce weak

and noisy signals and are more difficult for the receiver to track. Satellites below the minimum elevation angle are not tracked.

Low Multipath errors are caused when GPS signals are reflected

off nearby objects and reach the receiver by two or more different paths. The receiver incorporates the EVEREST multipath reduction option.

These corrections are broadcast from a Trimble 4000RSi™ or equivalent reference station.

Position Output

Geographic data obtained from different sources must be referenced to the same datum, ellipsoid, and coordinate format. Different formats provide different coordinate values for any geographic location. In North America, the datums NAD-27 and NAD-83 are commonly used in GIS mapping applications.

The AgGPS 114 receiver outputs position coordinates in several datums and ellipsoids depending on the source of DGPS being used. See Table 1.4.

Mounting the Receiver

To mount the receiver, secure the round magnetic base to a flat metal surface. To fasten the receiver to the surface, thread machine screws into the three M5 x 0.8 (5mm with 0.8mm pitch) metal inserts on the bottom of the receiver. The inserts are 10 mm (.39 inch) deep.

2.2.1

Choosing a location

When choosing a location, consider the following: Do mount the receiver:

• on a flat surface along the centerline of the vehicle or machine applicator boom.

• in any convenient location within 5.5 meters (18 feet) of the external instrument port. If necessary, use the optional extension cable to connect the receiver and external device.

• at the highest point of the vehicle with no metal surfaces blocking its view of the sky. Trimble recommends that you position the receiver on the top of a mast or pole.

• in such a way that it is not damaged when you drive the machine into a shed or storage area.

Do not mount the receiver:

• close to stays, electrical cables, metal masts, CB radio antennas, cellular phone antennas, air-conditioning units (machine cab blower fan), or machine accessory lights.

• near transmitting antennas, radar arrays, or satellite communication equipment.

• near areas that experience high vibration, excessive heat, electrical interference, and strong magnetic fields.

Note – A metal combine grain tank extension can block satellites.
