USER GUIDE
Thank you for choosing TeeJet Technologies’ RX520 as your GNSS receiver solution. This document provides instructions for mounting
and operation of the RX520. Contact a local dealer for more information or visit www.teejet.com.
Integrated GNSS Design
The RX520 provides an integrated L1/L2 GPS+GLONASS receiver and antenna in a single compact enclosure. Designed to meet or exceed stringent MIL-
STD-810G specications, the RX520’s rugged housing ensures high performance even in the most challenging work environments.
Multi-Constellation for Enhanced Positioning
Capable of tracking L1, L2 GPS+GLONASS and L-Band, the RX520 improves position availability in obstructed sky conditions.
Dual-frequency tracking minimizes the impact of ionospheric disturbances further enhancing eld productivity. Optional L-Band tracking improves
positioning accuracy outside of L1 SBAS coverage areas.
Smooth, Pass-to-Pass Accuracy with ClearPath® Technology
ClearPath technology is integrated into every RX520 antenna. ClearPath uses very accurate carrier phase calculations to provide ultra smooth positions
and excellent pass-to-pass accuracy for agricultural applications. ClearPath functions autonomously and with most available corrections services. It
will also bridge through short periods of poor satellite availability. ClearPath’s steady, smooth output is especially well suited for manual guidance and
autosteer installations.
BENEFITS
• Scalable for current dual constellation and future GNSS
systems
• Dual-frequency performance
• Smooth, consistent positions for pass-to-pass accuracy
• Rugged design for on-machine applications
FEATURES
• GPS and GLONASS satellite capability
• Built-in magnets for easy mounting
• Compatible with 12 V to 36 V vehicle power
• Ready to connect to any TeeJet Matrix, Matrix Pro, or
Aeros system. Matrix and Matrix Pro systems will require the
Power/CAN/Data cable [part number 45-05626 or
45-05845]

USER GUIDE
GETTING STARTED
This guide will assist in the set-up and operation of the RX520 GNSS receiver. The receiver will arrive ready to operate in the conguration that
was ordered. No further conguration will be required by the user. When the receiver is properly mounted with a clear view of the sky, and with the
connections for data and power completed, the unit will begin to provide positions. If using only GNSS (non L-band) solutions, position data will be
output within a few minutes of power-up. Allow approximately 15 minutes for quality SBAS positions and 20 minutes for PPP positions to be available.

RX520 LEDs
LEDs on the front of the RX520 provide basic receiver status information. The operation of the LEDs on the RX520 is summarized in the following table:
Icon LED Color State Description
Green Position Valid Indicates a valid GNSS position solution is available
!
Yellow Error
Receiver is in the error state and tracking is disabled
NOTE: Error status remains until the cause of error is corrected and receiver is reset.

LBAND SUBSCRIPTION
To subscribe to the Terrastar subscription L-band service:
1. Note the serial number of your RX520, the part number of the subscription that you intend to purchase, and the date that you want your subscription to
be activated.
2. Ask your dealer to contact TeeJet customer support for the TerraStar Subscription bulletin [98-01494] and provide this information. Your dealer will send
the order to TeeJet, and your nancial transaction will take place between you and your dealer.
NOTE: The minimum lead time for activation is 72 hours.
Your receiver does NOT need to be powered on at the time the subscription becomes active. The rst time you power your receiver on after the specied
activation date, it will become active on the subscription you have requested within several hours. During subsequent operation of your receiver, it will
typically require 15 minutes of operation with a clear view of the sky to fully process the L-band correction data and provide a GGA quality indicator value
of "5".

MOUNTING INSTRUCTIONS
The RX520 is equipped with four (4) built-in magnets for attaching to the included mounting bracket. The mounting bracket can be secured to the base
surface using traditional fasteners.
Intermediate Mounting Plate Template
A template for the intermediate mounting plate has been drawn in the
background of this user guide.
• Red lines indicate holes where attachment will occur.
• Green lines indicate the outline of the mount and other holes for
attaching the release plate.
Mounting Considerations
• Choose a location that has a clear view of the sky so that each satellite
above the horizon can be tracked without obstruction.
• When mounting the RX520 Receiver, a space of at least 15 cm between
the receiver and any bend in the cable is required. Any length shorter
than 15 cm puts undue stress on the cable and the enclosure for the
RX520.
• The receiver should not be mounted where water can pool around it.
The receiver housing is designed to withstand rain and splashing, but
not submersion in liquids for sustained periods of time.
• Mount the receiver above all other metal objects to avoid multipath.
Satellite signals received by the GNSS receiver by a reection from an
object can decrease positioning accuracy. For example, roof racks, large
headlight enclosures, etc., can cause multipath that may result in a jump
in GNSS position.
