To achieve specification, relevant differential corrections from a base station, NTRIP or TerraStar
subscription are required. The RTK accuracies are based on v2 products.

Accuracy is achieved using a four metre antenna separation (supports up to five metre separation).

10–18 V dc voltage levels apply to units with the 14P009 front panel fitted which was used in manufacture
prior to December 2011.

The operating temperature range for the antenna is much wider since it can be mounted outside the
vehicle. See specification below.
Notes on specifications
To achieve full accuracy in real-time, the RT products will require appropriate
differential corrections where applicable, either from a base station or with a TerraStar
license. Alternatively, a RINEX file can be downloaded post-mission and used to post-
process the data to full accuracy.
For the TerraStar service, at least 30 minutes of open-sky condition may be required
before full accuracy is achieved. This service can easily achieve this accuracy in airborne
applications.
The “1σ” specification has been used for parameters where offset cannot be measured
by the RT, for example position (the offset of the base station cannot be found by the RT
alone). The “RMS” specification was used where the offset is known, for example
velocity. For angles and measurements derived from the angles, the “1σ” specification
is used because the mounting of the RT compared to the vehicle gives an offset the RT
cannot measure.
The accuracy of the product will depend on the operating mode of the GNSS. For
example, an RT3002 operating without differential corrections enabled will have the
specifications of the RT3100.
