Data Collection For Post Processing - Novatel SMART7 Installation And Operation Manual

SMART7 with SPAN Operation

4.7 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:
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
From a rover:
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)
l
Post processing is performed through the Waypoint Inertial Explorer
able from the NovAtel Waypoint Products Group. Visit our Web site at
details.
The highest rate that you should request GNSS logs (RANGE, BESTPOS, RTKPOS,
PSRPOS, and so on) while in INS operation is 5 Hz. If the receiver is not running INS (no
IMU is attached), GNSS logs can be requested at rates up to 20 Hz.
