GNSS antenna (SMA, 1.5 m)
The GNSS antenna for the Navia Sense: an active multi-band antenna with an SMA connector on a 1.5 m lead, for the 25 Hz receiver and the signed IGC logs that depend on it.
- The antenna the Navia Sense ships with — as a spare, or the one a second Sense needs
- A shadowed antenna can cost the validity of a signed IGC file, not only tracking accuracy

Details.
The Navia Sense runs its GNSS receiver at 25 Hz, and a receiver is only as good as the antenna feeding it. This is the antenna the Sense ships with — an active, high-gain multi-band GNSS antenna on a 1.5 m lead with an SMA connector — supplied on its own as a replacement, or as the spare a second Sense needs.
Where it goes
On the outside of the fuselage, or under a non-conductive cover, with a clear view of the sky; never under a carbon or metal panel. It mounts horizontally with the GNSS marking up. Route the lead away from COM transceivers and their antenna cables.
Why it matters more on a Sense
The Sense's flight logs are digitally signed, and the signature depends on a continuous fix. An antenna in a shadowed position does not only cost you tracking accuracy — it can cost you the validity of an IGC file.
