NavSatCat

Navigation-satellite cataloguer for Wear OS

NavSatCat characterises what a device's satellite receiver can actually do. Rather than reporting a position, it enumerates the raw measurements the receiver produces — which constellations it tracks, on which frequency bands, and whether the measurements are good enough for precise work.

What it does

• Registers for raw GNSS measurements and reports every tracked satellite
• Names the constellation and frequency band per signal — L1, L5, E1, E5a, G1
• Reports carrier-to-noise density and baseband signal strength
• Shows pseudorange rate, tracking state and accumulated delta range state
• Dumps the receiver's declared capability flags, which frequently disagree with what it actually delivers
• Establishes whether carrier-phase measurements are valid — the question that decides whether precise positioning is possible at all

Data

NavSatCat writes no files and transmits nothing. Measurements go to the Android system log, readable only over a developer debugging connection by someone with physical access to the device. It uses location genuinely — raw measurements only flow while a positioning session is active — but records no coordinates. Full detail in the privacy policy.
