3kg! That's a very high price to pay for reliability under GNSS denied environments in the day time. Surely you can get ~altitude from a barometer, ~position from inertial + IMU + prior position, and if you want more accuracy maybe DEM models + topography is better.
Therefore I'd suggest this is not going to be very useful on anything with a view toward efficiency (drones). This is more likely a 'quick fix' plugin for existing fat-plane avionics for 'identified risk' reasons. OK move commercially, but technically meh. The go to market plan would presumably be FUD around GNSS denied situations. Reality: unlikely to be problematic in most cases (known flight path, high altitude, low GNSS-denied environment dwell time).

This is a one-time CapEx that will work for years and may allow you to fly (i.e., generate revenue) when otherwise you would be grounded: * https://www.cbc.ca/news/world/gps-interference-airlines-1.7213538 https://www.cbc.ca/news/world/gps-interference-airlines-1.72...
- constantcrying 1y agoIn a scenario where you have a conflict with completely denied GNSS (e.g. mass destruction of satellites) the applications are basically limitless. 3kg is perfectly viable on anything which isn't a small drone. Aircraft, ships, tanks, APCs, etc. all can use them.
- contingencies 1y agoGood use case. Although, they said the design is for planes. This is significant because the optics probably assume uninterrupted sky view with no interceding light sources which is an invalid assumption at ground level. If setting off a flare or cycling street lights is all it takes to deny positioning it's a weak terrestrial solution.
