Features
Read full description

GNSS Survey Logger is a simple field utility for saving GPS/GNSS-based measurement points and generating clean field reports directly from your iPhone. The app helps you record important location data during field work, site checks, surveys, technical visits, inspections, or documentation tasks. Main features: • Save measurement points with timestamp • Record latitude and longitude • Show coordinates in decimal and DMS format • Display altitude and accuracy values • Show local time and UTC time • Calculate visible GNSS satellite count from orbital data • Export saved points into a PDF Field Report • Share or save the report using the iOS share sheet Each saved measurement point contains the key data needed for later documentation, including coordinates, timestamp, accuracy, altitude, and visible GNSS satellite count. GNSS Survey Logger is designed for quick field logging, technical documentation, and simple survey-style reporting. Note: Visible satellite count is calculated from public orbital data based on current location and time. It is not raw receiver diagnostic data from the iPhone GNSS chipset.
