3.9 Data Collection for Post Processing
Some operations, such as aerial measurement systems, do not require real-time information from SPAN. These
operations are able to generate the position, velocity or attitude solution post-mission in order to generate a more
robust and accurate solution than is possible in real-time.
In order to generate a solution in post-processing, data must be simultaneously collected at a base station and
each rover. The following logs must be collected in order to successfully post process data.
From a base:
l
RANGECMPB ONTIME 1
l
RAWEPHEMB ONCHANGED
l
GLOEPHEMERISB ONCHANGED (if using GLONASS)
l
GALFNAVEPHEMERIS ONCHANGED (if using Galileo)
l
GALINAVEPHEMERIS ONCHANGED (if using Galileo)
l
BDSEPHEMERIS ONCHANGED (if using BeiDou)
From a rover:
l
RANGECMPB ONTIME 1
l
RAWEPHEMB ONCHANGED
l
GLOEPHEMERISB ONCHANGED (if using GLONASS)
l
GALFNAVEPHEMERIS ONCHANGED (if using Galileo)
l
GALINAVEPHEMERIS ONCHANGED (if using Galileo)
l
BDSEPHEMERIS ONCHANGED (if using BeiDou)
l
INSCONFIGB ONCHANGED
l
RAWIMUSXB ONNEW
l
HEADING2B ONNEW (if using ALIGN dual antenna solution)
Post processing is performed through the Waypoint Inertial Explorer
