Astro SB012 – Astro Software v2.1.13 addresses Service Bulletins SB010 and SB011

Date Released: September 10, 2025

Subject: Astro Software v2.1.13 addresses Service Bulletins

Effectivity: Immediate

Required Action: Urgent – Aircraft should be firmware updated

Affected Part Numbers: All Astro

BACKGROUND

Freefly has released two service bulletins in August 2025 to notify pilots of safety risks with existing flight software. Specifically:

– Astro SB010

– Astro SB011

Astro Software v2.1.13 is now released to address these service bulletins. Astro Release Notes can be found at https://freeflysystems.com/astroversions.

RECOMMENDATION

Aircraft should be updated to latest firmware immediately.

1. Follow these instructions to update Astro Software.
2. Follow these instructions to update Pilot Pro App, Firmware and AMC.
3. If flying with RTK or NTRIP, follow the instructions in the next section.

KNOWN ISSUE

RTK/NTRIP bursts can briefly drop GPS-assisted modes. Sudden, buffered RTCM corrections can delay GNSS processing for a few seconds, temporarily exiting Position/Auto/RTL.

Applies to: all currently released firmware, only when RTK or NTRIP is being used.

Mitigations:

• If you need RTK/NTRIP: set GPS_DUMP_COMM = Disabled (0)in AMC in advanced mode → Parameters. This limits GPS output so correction bursts cannot overrun processing. Note: while set to Disabled, PPK workflows are unavailable—restore this parameter to default when you need PPK.
• Status: Fix in progress for a follow-up patch.
