Important Notes

INAV 7 is the last INAV official release available for F411 based flight controllers. The next milestone, INAV 8 will not be available for F411 boards.

The GPS NMEA protocol is no longer supported. All pilots are required to switch to UBLOX protocol. All modern GPS modules (even as old as from 2015 and earlier) support UBLOX protocol and there is not a single good reason to stick to NMEA nowadays

Make sure to remove props and check your motor and servo outputs before powering your upgraded flight controller with a battery for the first time. The changes to enable flexible motor and servo allocation may change what outputs your configuration uses by default.

Upgrading from a previous release

Upgrading from INAV 7.0

  2. Download and install the new INAV Configurator 7.1
  3. Flash INAV 7.1 WITH Full Chip Erase option enabled
  4. Select Keep current settings from the defaults pop-up
  5. Go to CLI and restore your 7.0 diff
  6. Done

Upgrading from INAV 6 and 6.1

  1. Download and install the new INAV Configurator 7
  2. Save to a file the current diff all from the CLI.
  3. Upgrade to INAV 7 using the Full Erase option in the configurator.
  4. In case of Analog FPV, upload your OSD font of choice from the OSD tab.
  5. Go to the CLI again and paste the above-described contents from the file you previously created and write save , press ENTER.
  6. There are many new, changed, and removed settings. Check carefully that the settings are correct and fix any unrecognized or out-of-range items from the saved configuration.

Major changes

Fixed wing Autoland with landing pattern

INAV supports advanced automatic landings for fixed wing aircraft from version 7.1. The procedure is based on landings for man-carrying aircraft, so that safe landings at a specific location are possible. Supported are landings at Safehome after "Return to Home" or at a defined LAND waypoint for missions.
See: Fixed Wing Landing.md

Altitude and Heading estimation changes

INAV now relies more heavily on GNSS data for navigation than before. This can provide more security if the Barometer fails, or if the multirotor is suffering from Compass interference. By still allowing it to navigate back to home.
For more details see here

Other changes

Updated ICM426xx filtering

The filtering of the ICM426xx gyros has been updated based on changes made to both Ardupilot and BetaFlight and we expect better performance, when comparing to previous INAV versions.

Custom OSD

Users can now customize their own OSD messages, by way of the Programming Framework. Details

New Fixedwing flight mode

The mode is called Angle Hold. For more details see here

New targets

CLI

Changed settings

Name Description
gps_dyn_model Default: AIR_2G GPS navigation model: Pedestrian, Automotive, Air<1g, Air<2g, Air<4g. Default is AIR_2G. Use pedestrian/Automotive with caution, can cause flyaways with fast flying.

New Items

Name Description
ahrs_gps_yaw_weight Arhs gps yaw weight when mag is avaliable, 0 means no gps yaw, 100 means equal weight as compass Values: 0 - 500 Default: 100
nav_fw_land_approach_length Length of the final approach Values: 100 - 100000 Default: 35000
nav_fw_land_final_approach_pitch2throttle_mod Modifier for pitch to throttle ratio at final approach. In Percent. Values: 100 - 400 Default: 100
