5 Technical Data
5.1 Tracking Characteristics GG04
Satellite reception Multi-frequency
Instrument chan-
nels

Depending on the satellite systems and signals configured, a maximum number
of 555 channels is allocated.
Supported signals
*
Believe to comply, but subject to availability of BeiDou ICD and Galileo commercial
service definition. BeiDou B3 and Galileo E6 will be provided through future firmware
upgrade.
**
Support of QZSS is incorporated and will be provided through future firmware
upgrade when QZSS will be operational.
Initialisation time

Signal reacquisition
time (typical) < 1 s
5.2 Accuracy

Accuracy is dependent upon various factors including the number of satellites tracked,
constellation geometry, observation time, ephemeris accuracy, ionospheric distur-
bance, multipath and resolved ambiguities.
The following accuracies, given as r oot m ean s quare, are based on measurements
processed using Zeno Office and on real-time measurements.
The use of multiple GNSS systems can increase accuracy by up to 30% relative to GPS
only.
Post-processed
accuracy
*
Measurement precision, accuracy and reliability depend upon various factors
including number of available satellites, geometry proximity to base station, multipath
effects or ionospheric conditions.
