900 MHz RTK—Base Station Setup

System Overview

The StarFire™ RTK system consists of a local base

station placed in a field or mounted on a structure that

transmits high accuracy corrections to the vehicle StarFire

receiver using RTK radios. The StarFire receiver on the

RTK-equipped vehicle must have a direct line of sight with

the base station in order to receive the RTK signal.

Performance of the RTK system is related to the operating

distance from the base station. When operating beyond

20 km (12 miles), degraded accuracy will occur and it may

take longer to initially acquire the RTK signal.

A repeater, which is simply an RTK radio supplied with 12

volts of power, can be used to receive the base station

signal and establish a new line of sight point. However,

performance limitations can still be expected if trying to use

the repeater to transmit the RTK signal to a vehicle that is

farther than 20 km (12 miles) away from the base station.

NOTE: Old antennas from past receivers are not

compatible with the StarFire 3000 receiver.

Receiver—On Vehicle

Position receiver with integrated RTK radio module is

located on top of machine. Position receiver receives

global positioning and differential correction signal through

a single receiver and integrates signal for use with system.

The receiver has a dedicated operating mode (Vehicle

Mode). Refer to “Operating Mode—RTK” in “StarFire

3000” Section for setup of the receiver on vehicle.

Removing the antenna while transmitting

may damage the radio module.

IMPORTANT: The antenna must be installed before

the radio module is powered ON.

NOTE: Actual receiver position may vary with the use of

an Original Shroud or Deluxe Shroud bracket.

Avoid water intrusion by keeping the antenna

attached whenever possible.

900 MHz RTK—Base Station Setup

Receiver—On Base Station

The base station is the most critical part of an RTK system.

During installation, care must be taken to ensure the base

has problem-free operation. There are two issues that

are responsible for most problems with a base station:

Shading and Multipathing. If a base station experiences

one of these problems, it could be detrimental to your

RTK operation. Although it may not be possible to locate

a base station in an ideal location, this guide is aimed at

helping to define the best option available.

Base station operating mode can be either Absolute

Survey Base Mode or Quick survey Base Mode. Refer to

“Operating Mode—RTK” in “StarFire 3000” Section for

setup of the receiver on base station.

Refer to “Base Station Operation and Setup” in “StarFire

3000” Section for proper use and setup of the base station.

900 MHz RTK—Base Station Setup

Repeater Radio

The radio can be configured to act separately as a

repeater. A repeater is required if obstructions (i.e. trees,

hills, etc.) exist between the base station and vehicle(s) or

if base station is too far away from the vehicles.

A repeater consists of:

• Radio (configured as a repeater)

• Harness

• Mounting Bracket

• 12 Volt Power Source

• Tripod or wall mount cradle

IMPORTANT: A repeater can only be used to repeat

a signal from a base station to a vehicle.

Therefore, a repeater cannot be used in a

''daisy chain,'' repeating the signal from

one repeater to another.

Refer to “Repeater—RTK” in “StarFire 3000” Section to

properly configure radio as repeater.

900 MHz RTK—Base Station Setup

When selecting a base station location, there are three

main points to look for: rigidity, good view of the sky,

and few reflective objects. The base station provides

corrections to the vehicle receiver based on the fixed

known position which is surveyed in with an absolute

survey or quick survey. Any motion of the base station

receiver will translate directly to the vehicle position.

Mount the base station on a rigid structure, such as the

pole in the photo. When mounting on a structure such as

a building, the receiver should generally be installed 2

meters above the highest point.

Multipathing

Signal reflections are another important error source

for base stations that should be minimized. Reflected

signals also reach the base station receiver and make

the satellite range measurement longer. Reflections can

even interfere with the direct signal enough so that the

receiver will temporarily lose lock on the satellite. Metal

buildings, chain-link fences, and bodies of water are all

good reflectors that can make a base station less reliable.

Take care to place your base station receiver far away

from strong reflectors for reliable base station operation.

A base station should have a continuous 12V power

source such as an AC/DC converter to power the base

station. A battery back-up is recommended to keep the

base station running in the case of power outages for

dependable operation.

NOTE: The AC/DC converter is not supplied

by John Deere.

In order to maintain a good RTK Radio link, the antenna

must be mounted high enough to radiate over the earth’s

curvature and any obstacles. As shown in the figure, the

curve of the earth can block the signal from the RTK link.

If the radiating base station radio antenna is mounted too
