Notes

L5 (Triple Frequency), GLONASS, GALILEO, BeiDou GNSS[10]4 GB Internal Data Logging. Moving Base and Heading
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, interference and atmospheric conditions.
Always follow recommended survey practices.
3 Depends on SBAS system performance.
4 May be affected by atmospheric conditions, signal multipath, and satellitegeometry. Initialization reliability is continuously monitored to ensure highestquality.
5 If your receiver is transmitting 2.0 W (450 MHz), 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 SPS986 with Moving Base installed orother suitable SPS receivers.
8 Galileo Commercial Authorization
Developed under a Licence of the European Union and the European SpaceAgency.
9 Networked RTK PPM values are referenced to the closest physical basestation
10 This Trimble SPS Receiver is capable of supporting existing and planned
GNSS satellite signals, including GPS, GLONASS, GALILEO, BeiDou andQZSS, and existing and planned augmentations to these GNSS systems.
11 RTK refers to the last reported precision before the correction source waslost and xFill started
12 Receiver accuracy and convergence time varies based on GNSS
constellation health, level of multipath, and proximity to obstructions such aslarge trees and buildings.
13 Proper survey techniques should be followed to reduce multipath error andmaintain a good line of sight to the sky for satellite tracking. At greater than 30°of tilt, accuracy at the rod tip may decrease more than specified.
