Modular GPS Receiver
1 Receiver will operate normally to those temperature limits. Internal batteries will
operate from –20 °C to +48 °C
2 Accuracy and reliability may be subject to anomalies such as multipath,
obstructions, satellite geometry, and atmospheric conditions. Always follow
recommended survey practices.
3 Depends on SBAS system performance.
4 May be affected by atmospheric conditions, signal multipath, and satellite
geometry. Initialization reliability is continuously monitored to ensure highest
5 If your receiver has the 2.0 W upgrade, you will experience reduced battery
performance compared to the 0.5 W solution.
6 Bluetooth type approvals are country specific. For more information, contact
your local Trimble office or representative.
7 When receiver is combined with an SPS552H or other suitable SPS receivers.
8 Galileo Commercial Authorization
Receiver technology having Galileo capability to operate in the Galileo frequency
bands and using information from the Galileo system for future operational
satellites is restricted in the publicly available Galileo open Service Signal-InSpace Interface Control document (GAL OS SIS ICD) and is not currently
authorized for
commercial use.
Receiver technology that tracks the GIOVE-A and GIOVE-B test satellites uses
information that is unrestricted in the public domain in the GIOVE A + B
Navigation Signals-In-Space Interface Control document. Receiver technology
having developmental GIOVE-A and B capability is intended for signal evaluation
and test purposes.
9 Networked RTK PPM values are referenced to the closest physical base station
