A customer flying a Skybrush light-show fleet sent us a puzzle in October: every drone carrying an MA-RTK-AIR-626 RTK module had a perfect RTK FIXED solution and passed its pre-arm checks, yet Skybrush Live flagged each one with a yellow TIMESYNC warning. The cause turned out to be one missing number. The 626 never sends the GPS week, and ArduPilot's u-blox driver has no other place to find it. This is the story of how we traced it, why no setting could fix it, and how we changed the firmware and tested the change before it went near a show. The step-by-step fix and the firmware downloads for 20 flight controllers are in the MA-RTK-AIR-626 Skybrush guide.

For as long as open-source drones have flown indoors, "VIO" has meant a project: a RealSense camera, a Raspberry Pi or Jetson, ROS, a VIO package, a MAVLink bridge, and a week of getting them to agree with each other. MicoVIO, launched by MicoAir on 15 October 2026, collapses all of that into a 16-gram module that plugs into a spare UART on an ArduPilot or PX4 flight controller and streams position, velocity and attitude as standard MAVLink 2 ODOMETRY messages. No companion computer, no SDK, no calibration routine.

We sell and support 915 MHz radios, GPS/RTK modules, optical-flow and laser range sensors across North America — and we kept hearing the same thing from customers: the clear, practical English documentation they needed simply didn't exist. So we're writing it ourselves.

We're starting with 915 MHz telemetry radios because that's what most of our customers reach for first — and because a lot of people buy an LR900 not as a "drone part" at all, but as a dependable long-range 915 MHz serial link: RTK base-to-rover, sensor backhaul, and plain point-to-point links between two devices.
