Release 2.46, August 26th 2014 |
|
------------------------------ |
|
|
|
The ardupilot development team is proud to announce the release of |
|
version 2.46 of APM:Rover. This is a major release with a lot of new |
|
features and bug fixes. |
|
|
|
This release is based on a lot of development and testing that |
|
happened prior to the AVC competition where APM based vehicles |
|
performed very well. |
|
|
|
Full changes list for this release: |
|
|
|
- added support for higher baudrates on telemetry ports, to make it |
|
easier to use high rate telemetry to companion boards. Rates of up |
|
to 1.5MBit are now supported to companion boards. |
|
|
|
- new Rangefinder code with support for a wider range of rangefinder |
|
types including a range of Lidars (thanks to Allyson Kreft) |
|
|
|
- added logging of power status on Pixhawk |
|
|
|
- added PIVOT_TURN_ANGLE parameter for pivot based turns on skid |
|
steering rovers |
|
|
|
- lots of improvements to the EKF support for Rover, thanks to Paul |
|
Riseborough and testing from Tom Coyle. Using the EKF can greatly |
|
improve navigation accuracy for fast rovers. Enable with |
|
AHRS_EKF_USE=1. |
|
|
|
- improved support for dual GPS on Pixhawk. Using a 2nd GPS can |
|
greatly improve performance when in an area with an obstructed |
|
view of the sky |
|
|
|
- support for up to 14 RC channels on Pihxawk |
|
|
|
- added BRAKING_PERCENT and BRAKING_SPEEDERR parameters for better |
|
breaking support when cornering |
|
|
|
- added support for FrSky telemetry via SERIAL2_PROTOCOL parameter |
|
(thanks to Matthias Badaire) |
|
|
|
- added support for Linux based autopilots, initially with the PXF |
|
BeagleBoneBlack cape and the Erle robotics board. Support for more |
|
boards is expected in future releases. Thanks to Victor, Sid and |
|
Anuj for their great work on the Linux port. |
|
|
|
- added StorageManager library, which expands available FRAM storage |
|
on Pixhawk to 16 kByte. This allows for 724 waypoints, 50 rally |
|
points and 84 fence points on Pixhawk. |
|
|
|
- improved reporting of magnetometer and barometer errors to the GCS |
|
|
|
- fixed a bug in automatic flow control detection for serial ports |
|
in Pixhawk |
|
