Collector for ArcGIS - High Accuracy, Powered by Bad Elf
Bad Elf has been working with the Collector for ArcGIS team at Esri to provide reliable and highly accurate location services directly to the Collector for ArcGIS mobile applications across various platforms (iOS, Android, and Windows). The Bad Elf GNSS Surveyor was designed and built to provide mapping grade accuracy of about one meter when used with the built-in SBAS + PPP. The GNSS Surveyor receiver, combined with Collector for ArcGIS, delivers an affordable solution for GIS data collection and mapping with the benefit of higher accuracy.
With the new high performance features built directly into the Collector for ArcGIS app, Bad Elf now supplies additional metadata directly; maximizing the quality of your field data.
- Full autonomous navigation in or out of cellular coverage
- Metadata support including Horizontal RMS, Vertical RMS, Fix Type, Satellite Visibility, PDOP, HDOP, VDOP
- Simple configuration - no third party apps required
- Native support for accuracy minimums and coordinate transformation (through Collector)

Between these two extremes lies mapping grade GPS, which delivers 1 meter accuracy.
