Licensing of 450 MHz RTK Base Licensing of 450 MHz RTK Base The 900 MHz RTK product sold by John Deere uses ISM band radios. These radios do not require licensing by the end user. The radios are limited to a specific frequency range and 1 W maximum output power. While this system works for the majority of applications, the reliability of the RTK link may become limited when passing through trees and dense foliage. The intent of 450 MHz RTK is to increase the range and reliability of the RTK link.
RTK Base Station Setup System Overview The StarFire™ RTK system consists of a local base station permanently mounted on a structure that transmits high accuracy corrections to the vehicle’s StarFire™ receiver using 450 MHz RTK radios and an optional amplifier. 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.
RTK Base Station Setup Vehicle Receiver Position receiver with integrated RTK radio module is located on top of machine. Position receiver combines the global positioning signals it receives with the RTK differential correction via the radio link to provide accurate position information to the GreenStar™ system. The receiver has a dedicated operating mode (Vehicle Mode). Refer to Operating Mode—RTK in Section StarFire iTC for setup of the receiver on vehicle.
RTK Base Station Setup Base Station Setup The base station is the most critical part of RTK system. During installation, care must be taken to ensure the base has problemfree 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. These issues are shared with the 900 MHz RTK system.
RTK Base Station Setup Base Station Setup—Amplifier Option CAUTION: Install and operate the amplifier safely. Read and follow PREVENT ELECTRICAL SHOCK AND FIRES and AVOID EXPOSURE TO HIGH RADIO FREQUENCY FIELDS in the SAFETY section. The primary reason for 450 MHz RTK is to provide a more robust RTK data link. Signal strength is the dominant factor in the link reliability and range. For areas where there are trees and other foliage, John Deere offers an optional inline amplifier.

RTK Base Station Setup PUPC000007 —UN—03DEC09 The ability to use a single base station is a substantial reduction in cost and maintenance. The drawback to this method is that only one radio can be configured at a time. A single RS232 port is used by the StarFire™ receiver to communicate with an RTK radio. Two radios can simultaneously receive RTK corrections from the receiver. Unfortunately, the receiver can not process simultaneous messages sent from the radios.
RTK Base Station Setup PUPC000009 —UN—03DEC09 The 900 MHz RTK message rates are designed with extra redundancy. System performance is not compromised at 2 Hz message rate. Both 900 MHz and 450 MHz RTK systems have sufficient redundancy to ensure RTK reliability and accuracy. The diagnostic reading on vehicles with 900 MHz radios will be based on 5 Hz message rate. The result is that 900 MHz customers receiving corrections from base with a narrowband L2 attached will be 40% data received at best.
RTK Base Station Setup Radio Power Setting to Meet Licensed ERP The 450 MHz RTK system has been designed to meet a wide range of possible configurations. This gives the end user the ability to optimize the system for their specific location and application. The end user must obtain a site license from the local spectrum authorities. It is the end user’s responsibility to ensure that 450 MHz RTK system parameters are configured correctly.
GS2 Display iTC—450 MHz RTK PC8663 —UN—05AUG05 RTK SoftKey 450 MHz RTK is supported by VI displays. These include GreenStar 2 System™ Displays and SDUA.

GS2 Display iTC—450 MHz RTK Screens Common to Standard and 450 MHz RTK When RTK is in the OFF mode, the main pages are common between the two systems. The details of these particular pages are provided in the StarFire iTC and RTK Operator’s Manual. This manual was provided with the purchase on an iTC receiver. When in VEHICLE or BASE mode, the pages for 450 MHz RTK system vary slightly from the pages for 900 MHz RTK system.

Diagnostic LEDs Diagnostic LEDs A key aid to gain insight into the working state of the 450 RTK system are the LEDs on both the RTK radio and the inline amplifier. These diagnostic lights can be used during setup, maintenance and troubleshooting. SH20560,0000124 1904DEC091/1 450 MHz RTK Radio LEDs PUPC000021 —UN—06DEC09 There are three radio LEDs. They can be seen after the radio has been powered. They are viewed through a small window on the front of the radio.
Diagnostic LEDs Amplifier LEDs There are four amplifier LEDs. They are located on the side of the amplifier. The LEDs can be used to determine □ Is the amplifier powered? □ Is there an internal failure? □ Is the radio signal being amplified? □ Is the amplifier setup causing it to overheat? □ Is the antenna or its connection path faulty? The LEDs operate in two states: Start Up and Operation.
450 RTK Performance 450 MHz RTK Accuracy The accuracy of 450 MHz RTK is the same as 900 MHz RTK. The UHF link is more robust, but the content sent by the StarFire RTK™ base to the vehicle is identical. StarFire RTK™ delivers 1 in. repeatable accuracy. RTK accuracy is expressed as an absolute value (without +/) because RTK performance is not subject to GPS drift over time. RTK accuracy levels are described on a static basis measured at the vehicle receiver, 68 percent of the time, within 12 mi.
450 RTK Performance PC9393 —UN—23OCT06 Line of Sight Line of sight is the direct path between two points, free of obstacles. For the RTK application, this is the line between the base and vehicle antennas. Typical obstructions include: • Trees and foliage • Buildings or other manmade objects • Terrain variation, such as hills or valleys • Curvature of the Earth 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.
450 RTK Performance 12.5 kHz versus 25 kHz Bandwidth There are two possible bandwidths that can be set in the 450 MHz RTK radio: 25 kHz Wideband 12.5 kHz Narrowband The 25 kHz bandwidth delivers twice the baud rate of the 12.5 kHz. Wide bands have more data capacity and faster message transmission than narrow bands. In the RTK system, this results in a more robust data link. However, the disadvantage to using a larger bandwidth is that fewer licensed frequencies are available to applicants.
