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
|
|

|
|
|
|
|
|
|

|
|
|
|
|
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

|
|
|
|
|
view of the sky
|
|
|
|
|

|
- 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.
|
|
|
|
|
|
|
|
