Bad Elf GNSS Surveyor

BAD ELF GNSS SURVEYOR
BLUETOOTH GNSS RECEIVER & DATALOGGER WITH BAROMETRIC SENSOR

The Bad Elf GNSS Surveyor delivers ~1 meter positioning out of the box to the iPad for use in GIS, mapping, agriculture, and survey activities. The GNSS Surveyor can record raw data and produce RINEX through the Bad Elf application for your post-processing needs.

Supports Differential GPS (DGPS) Corrections
Post Processing Ready

MAPPING-GRADE GPS, POWERED BY BAD ELF
The GNSS Surveyor is the most affordable 1 meter GNSS receiver available on the market today, and it works with a variety of GIS apps. Looking to learn more about use in GIS, see our GIS Resources for detailed information and advanced usage.

APP SUPPORT
The GNSS Surveyor works out of the box with all location services aware iOS apps, but apps that integrate the Bad Elf SDK can access the advanced data and features available for sub-meter accuracy. Bad Elf has begun working with several developers to support the GNSS Surveyor directly.

AFFORDABLE & SIMPLE TO USE
At Bad Elf, we strive to create high quality, dependable products consistent with Apple's philosophy of "It just works!" Just turn on your Bad Elf GNSS Receiver and get to work. No complicated setup. Extra long battery life. No hassles.

GIS/MAPPING FEATURES

Stationary high precision GNSS as low as 1m out of the box with PPP in regions with SBAS coverage
Post-processing support via RINEX conversion available in the Bad Elf app
Differential GPS (DGPS) supported using Internet delivered RTCM 2.3 via built-in NTRIP client.
56 channel receiver supports GPS (US) and QZSS (Japan) constellations with SBAS (WAAS/EGNOS/MSAS), or GLONASS (Russia)
Obtain altitude from GPS or from the built-in barometer, which can be calibrated to a known altitude or pressure
No internet connection or monthly subscription required

RECEIVER FEATURES

View GPS or GLONASS status quickly with the backlit LCD
All day battery life allows you to track for up to 35 hours (24 hours when streaming over Bluetooth)
Access data logs directly from any PC or Mac using the included USB cable. GPS appears just like a USB thumb drive
USB connectivity to PC or Mac provides streaming data, raw or NMEA

ACCURACY STATEMENT
Bad Elf performs a variety of controlled tests on each product to test expected performance. Factors such as satellite geometry, multi-path, environmental conditions are considered in our testing process. Statements of accuracy are in ideal, or near ideal conditions, using best practices for field data collection.

GPS+PPP+SBAS ACCURACY
The GNSS Surveyor is capable of producing 1 meter CEP positional accuracy using GPS+PPP+SBAS. uBlox states that "PPP technology is made possible by stabilising measurements of the distance between GNSS satellites and the receiver (pseudo-ranges) using carrier phase tracking. Additional accuracy is achieved from ionospheric correctional data received from satellite-based augmentation systems.
