## What is GNSS Planning Map?

GNSS Planning Map shows you, before you leave the office, when and where satellite geometry (DOP) will be good or poor. Drag a time-travel slider and watch a DOP heatmap turn green or red across the map — so you never arrive on site only to find the constellation is too weak to get a fix.

Try every feature free for the first month, right on your phone.

[ Main features ]
- DOP forecast heatmap: see how PDOP and the visible-satellite count change through the day across an area, from green (good) to red (poor).
- Time-travel slider: jump to "next Thursday 14:30" and read the sky instantly. Orbits come from CelesTrak TLE with SGP4/SDP4 propagation.
- Tap any point for an instant GO / NO-GO: PDOP, satellite count, and a per-constellation breakdown for that exact site and time.
- Configurable rules: turn each constellation on/off (GPS, QZSS, GLONASS, Galileo, BeiDou, NavIC), set the elevation mask, minimum satellites and a PDOP limit. Presets for public survey and UAV RTK.
- PDF work-order / evidence export (Pro): save a site and its recommended work windows as a one-page report.
- Field-ready: once data is cached the forecast works offline.

[ Who it is for ]
Land surveyors, UAV / drone mapping and inspection teams, and GIS / infrastructure crews who plan RTK/PPK sessions and want to avoid wasted trips and reschedules.

[ Honest notes ]
The core forecast (orbits to DOP to heatmap) is global and works anywhere. This app is a planning aid based on orbital prediction; it does not guarantee field results — always verify on site.
