5 Using the GNSS receiver
Receiving signals from GNSSsatellites
To receive signals from GNSS satellites, the handheld must have a clear view of the sky. GNSS positions
may not always be available, particularly in or near buildings, in vehicles, or under tree canopy.
For optimal GNSS reception, hold the handheld at 15° from horizontal allowing it visibility of the sky. When
collecting point data with a MobileMapper 60 handheld, it is recommended that you remain stationary at
the point for at least 10 seconds before beginning to log GNSS positions. This allows the GNSS receiver’s
internal algorithms to stabilize, and ensures the best possible point feature accuracy.
The GNSSreceiver supports all three available SBAS correction services (WAAS in North America, EGNOS
in Europe, and MSAS in Japan).
Using GNSS enables the handheld to determine your location with < 2 meter accuracy in open sky (with
SBAS), and enables geo-tagging of photos you take using the handheld's integrated camera (see Using
the camera, page 46 for more information on enabling geotagging and taking photos).
To use theGNSSreceiver:
1. Tap Settings / Security &Location.
2. Tap Location and tap the Off / On slider to On.
3. Tap Mode then select the mode you want the device to use to determine your location:
l High accuracy. Uses GNSS satellites, Wi-Fi, and cellular networks to determine your location.
l Battery saving. Uses Wi-Fiand cellular networks to determine your location.
l Device only. Uses GNSSonly to determine your location.
4. Tap the back arroww, then tap NMEAMode to turn it on or off.
5. Tap SBAS mode to turn it on or off.
6. Tap GNSSmode then select the mode you want the device to use (GPS only; GPS +BDS; GPS +
GLONASS; GPS + BDS + Galileo, GPS + GLONASS + Galileo, GPS + Galileo).
Supported software
Spectra Geospatial provides both GIS and Survey applications to run specifically on the MobileMapper 60:
l MobileMapper Field for Android for GIS
l Survey Mobile for survey
l Penmap for Android
The MobileMapper 60 handheld can be used with any Android application. A wide range of application
software is compatible with the Android 8.0 operating system and spatial data available through the
Google Location Services API, including many GNSS navigation and data collection applications. To
access spatial data from the internal GNSS receiver of the MobileMapper 60 handheld, an application
must support one or more of:
l Android Location Services API
l NMEA-0183 ASCII protocol
