From forum, I found that Kpsi is not updated (although the heading is corrected), so is P associated with heading. This version fixes this problem. In addition to that, since Stargate is not available any more, this version is compatible with Gumstix compiler (at least it works in my gumstix setup).
MNAV v1.4 works with Ground Station v1.1 only.
The major modification of v1.4 is the Kalman filter section for Heading determination and the communication (from TCP/IP to UDP protocol) section.
Ground Station v1.1 adds the UDP protocol for MNAV v1.4.
The MNAVs with old firmwares have un-intuitive
servo mappings. The latest firmware (version 1.3)
resolves this issue. With this firmware,
the servo mapping follows the R/C standard.
For those who have the firmware version of
8160-0035-03_A, download version 1.3 (8160-0035-03_B)
and update the firmware. That's it!
For those who have different firmwares, two steps are required:
1) download the firmware and upload it.
2) Pull out your calibration sheet that came with
the the MNAV and retype these numbers to
Calibration section of MicroView 2.0
that you need to download,
or recalibrate the unit using MicroView 2.0.... read more
