(1) Product is designed to fully support GLONASS L1/L2 CDMA and BeiDou B3
signals as soon as the officially published signal Interface Control
Documentations (ICD) become available..
(2) Secondary GNSS antenna input is dual-frequency only (no GPS/SBAS/
IRNSS L5, no Galileo E5a, E6, no Beidou B3, no GLONASS L3).
(3) All available GNSS signals are processed equally and combined without
preference to any particular constellation for optimal performance in harsh
environment.
(4) 50 Hz output is available as firmware option (20 Hz output is a standard
feature). At 50 Hz, a limited set of messages can be generated simultaneously
through a single port.
(5) RTCM-3.2 Multiple Signal Messaging (MSM) guarantees compatibility with
3rd party for each GNSS data.
(6) ATOM: Open Ashtech format.
(7) VRMS for Autonomous/SBAS positions are usually twice as high as HRMS.
(8) Heading latency is usually twice as high.
(9) As required by the U.S. Department of Commerce to comply with export
licensing restrictions.
(10) Accuracy and TTFF specifications may be affected by atmospheric
conditions, signal multipath and satellite geometry.
(11) Performance values assume minimum of five satellites, following the
procedures recommended in the user guide. High multipath areas, high
PDOP values and periods of severe atmospheric conditions may degrade
performance.
(12) Network RTK PPM values are referenced to the closest physical base
station.
(13) Requires L1/L2 GPS+GLONASS at a minimum.
(14) Accuracy and TTFF specifications may be affected by atmospheric
conditions, signal multipath, satellite geometry and L-band service
availability. Trimble RTX correction services are only available on land.
(15) Accuracy and TTFF specifications may be affected by atmospheric
conditions, signal multipath, satellite geometry and corrections availability
and quality
(16) L1/L2 data required.
(17) Figures of pitch accuracy are twice as high.
