10.12 Differential and RTK GNSS
Spatial supports receiving differential corrections to enhance position accuracy. Spatial
hardware version 7.0 and above also supports RTK corrections. The corrections must
come from a base station located within a 25 km radius of where the Spatial unit is
operating. There are many companies worldwide that provide nationwide network
corrections services from a local base station that can be received over the internet
using a protocol called NTRIP.
Spatial Manager has an NTRIP client built in that can connect to the network
corrections service to receive the corrections and feed them into the Spatial unit.
Please see section 11.9.5.
The corrections format supported is RTCM v3.
10.13 Raw Satellite Data
Spatial hardware version 6.1 and above features a new GNSS receiver that is capable
of outputting raw satellite data. This raw satellite data can be used by post-processing
programs to achieve high accuracy kinematic positioning.
The maximum output rate for raw satellite data is 10Hz and it can be enabled by
turning on the Raw Satellite Data Packet (ID 60) in the packet rates dialogue in Spatial
Manager, see Illustration 21. This packet will be automatically converted to RINEX
v3.02 by Spatial Managers log converter utility.
10.14 Post Processing
Spatial hardware version 6.1 and above can be used with Advanced Navigation’s post
processing platform Kinematica to achieve high accuracy kinematic positioning of
