Navigation Processing
Have processed IPAS navigation on IPAS TC (this is the nav system attached to the Owl).
SNEO (OS) basestation used, precise ephemeris and clock accessed from CDDIS.
Position seperation is largely within ~+/- 0.2m in X, Y & Z.
Note Flight was planned to align with OS Basestation ALDB. Use this when processing with correct leverarms.

All lines mapped to 3 bands.
aplnav error when processing line 5 & 6. Below is error message for line 5:
########## ERROR ######### Time goes backwards in navigation file at epoch 7059 Previous time: 220983.0001 Current time: 220983.0001 If this occurs in a .nav file then it is probably OK to continue if you are not outputting the real-time navigation. To try and force APL to continue use the -force command line option. ########## ERROR #########
Different aplnav Error when processing line 8
########## ERROR ######### Frame number is less than current sync message frame. This cannot yet be handled, there may be an error with the nav file. Contact developers for information. ########## ERROR #########
Using -firstonly argument prevents both these errors.
Hard to tell geoaccuracy as flightlines are over open ocean. Flight 1 is over the Greater Gabbard windfarm and there are some turbines visible but I'm not sure of their exact true locations. They are shown on OpenStreetMap but it doesn't line up well with the Owl data, but I have nothing to suggest the OpenStreetMap locations are accurate.

anla is doing the delivery check.

Ready to Deliver
anla has done the checks. All looks good. I have updated the readme to mention the low signals over the ocean and the lack of features to verify the geoaccuracy.
