USER GUIDE
Thank you for choosing TeeJet Technologies’ RX720 as your GNSS receiver solution. This document provides instructions for mounting and operation of
the RX720. Contact a local dealer for more information or visit www.teejet.com.
RX720 GNSS receiver delivers the latest in positioning technology for agricultural applications. This state-of-the-art smart antenna receives multiple GNSS
signals to deliver better satellite availability under challenging terrain and environmental conditions.
Accuracy, Stability and Reliability
The RX720 can deliver the positioning accuracy needed for your precision farming applications. This exible receiver can be congured to deliver
basic performance using free correction signals, and can also be upgraded to use subscription-based satellite corrections or RTK for more demanding
applications. TerraStar services provide 19.7 in / 50 cm (TerraStar-L) or 1.2 in / 3 cm (TerraStar-C PRO) level accuracy (95%) using globally transmitted
satellite correction signals. ClearPath technology is integrated into the receiver and provides smooth positions and excellent pass-to-pass accuracy that
are ideal for agricultural guidance and steering applications.
Multi-Signal, Multi-Frequency, Totally Flexible
A high-quality internal antenna element combined with the ability to track 555 channels make the RX720 extremely exible. This receiver can receive
GPS, GLONASS, BeiDou, Galileo and QZSS, along with TerraStar correction signals. This results in high numbers of satellite signals and a wide range of
congurations that can deliver the accuracy your application needs – from subscription free SBAS (WAAS, EGNOS, MSAS, GAGAN) corrections through
TerraStar-L and TerraStar-C PRO, and even centimeter-level RTK accuracy.

USER GUIDE
GETTING STARTED
This guide will assist in the set-up and operation of the RX720 GNSS receiver. With the exception of use in RTK applications, the receiver is
shipped from TeeJet ready to operate in the conguration ordered. 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 Single Point (Autonomous) 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 L-band positions to be
available.

RX720 LED
LED on the side of the RX720 provides basic receiver status information. The operation of the LED on the RX720 is summarized in the following table:
State Description
Green Solid Precise solution good (RTK/PPP or Fixed)
Green Slow Flash (1Hz) Precise solution converging
Yellow Solid Basic solution (Single Point/SBAS/DGPS)
Yellow Slow Flash (1 Hz) Tracking satellites and calculating initial position solution
Yellow Fast Flash (3 Hz) Initialised and ready for communication
Red Solid (Initial) Power On/Reset (for about 10 seconds after power-on or reset)
Red Solid (Continuous) Receiver system error, if indicator persists after 30 seconds
Red Slow Flash (1 Hz) Position quality warning (unreliable/high error)
Red Fast Flash (3 Hz) Positioning failure (unusable)
LBAND SUBSCRIPTION
To subscribe to the TerraStar subscription L-band service:
1. Note the serial number of your RX720, 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.
The receiver does NOT need to be powered on at the time the subscription is activated. The rst time you power the receiver on after the specied
activation date, the subscription activation will be captured by the receiver over-the-air within 4 hours of being powered on. During subsequent operation
of the receiver, it will typically require 20 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 "2" (TerraStar-L) or "5" (TerraStar-C PRO).

MOUNTING INSTRUCTIONS
The RX720 is equipped with three (3) built-in magnets for attaching to the included mounting bracket. If a permanent mount for the RX720 is required
please contact TeeJet Technologies Technical Support for more information.
Intermediate Mounting Plate Template
A template for the intermediate mounting plate has been drawn in the
background of this user guide.
• Red circles 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 RX720 Receiver, a space of at least 5.9 in / 15 cm
between the receiver and any bend in the cable is required. Any length
shorter than 5.9 in / 15 cm puts undue stress on the cable and the
enclosure for the RX720.
• 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.
