GCM Survey turns your iPhone or iPad into the screen, the control panel and the safety net for your Geosensors data logger. Join the logger's own Wi-Fi network and you have the whole survey in your hands — no internet, no cables, no laptop in the field. LIVE SURVEY MONITORING See the survey as it happens. Your track draws itself on the map in real time, rotating course-up as you walk the line so the display always matches the direction you're facing. Live EM traces, GPS quality, satellite count, battery voltage, temperature, pitch and roll are all a tap away while you record. PRE-FLIGHT CHECK BEFORE YOU START Data is flowing before you press Start, so the readiness panel tells you what the logger can actually see: EM sensor live and how many separations, GPS fix quality, free storage. Catch a dead sensor or a bad fix at the truck instead of at the end of the line. FULL CONTROL OF THE LOGGER Start, pause, resume and stop surveys from your phone. Pauses are recorded properly — the track breaks where you stopped and picks up where you resumed, so distance and duration never count the walk back to the truck. SPOKEN ALERTS Eyes on the ground, not on the screen. The app speaks up when something needs you: a card error, a receiver overflow, storage running low, or a data source that has gone quiet. Mute it any time. IT SURVIVES INTERRUPTIONS The logger is the source of truth and it keeps recording no matter what your phone does. Walk out of range, get a call, relaunch the app — reconnect and the app rejoins the survey in progress, refetches only the bytes it missed and redraws the full track. A dropped packet or a missed poll is never treated as a lost survey. Phone battery dies mid survey? Simply connect a different phone or iPad to the same logger and continue as you were. FINISH AND REVIEW IN SECONDS Because the app captures data live as you record, there's no long download at the end. Stop the survey and the summary is already there: sample count, distance, duration, average speet, GPS quality and EM channel coverage. Every finishedsurvey is verified byte-for-byte against the logger's own checksum before you keep it, then saved or discarded with one tap. CHARTS AND EXPORT Plot EM waveform channels for any survey on the devicrt and share in the format your processing softwarewants: • NMEA — the raw sentence stream • XYZ — tab-separated, with UTM easting and northing • LOG — legacy tab-separated columns • CSV — dated, full-channel CSV Share straight to Files, Mail, AirDrop etc. MANAGE THE LOGGER Browse, import, rename and delete files on the logger's SD card, check free space, set the device clock, configure serial port baud rates, and change the logger's name, Wi-Fi network anSettings screen. Firmware updates are guided step bystep, with the app reconnecting and confirming the new version for you when the logger comes back up. BUILT FOR THE FIELD Designed for iPhone and iPad. Everything works entirely offline over the logger's own Wi-Fi. Requires a Geosensors GCM Logger. Contact support@geosensors.com with any questions.
