Notes 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
quality.
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 SPS555H or other suitable SPS receivers.
SPS855 must have Moving base option installed
8 Galileo Commercial Authorization
Developed under a Licence of the European Union and the European Space
Agency.
9 Networked RTK PPM values are referenced to the closest physical base station
10 This Trimble SPS Receiver is capable of supporting existing and planned
GNSS satellite signals, including GPS, GLONASS, GALILEO, BeiDou and QZSS,
and existing and planned augmentations to these GNSS systems.
11 RTK refers to the last reported precision before the correction source was lost
and xFill started
