Abstract:This presentation, which was given during the GPS-ABC Workshop VI in Washington, DC on March 30, 2017 details the authors' radiated testing protocols and results. GPS receiver testing was carried out April 25-29, 2016 at the Army
Research Laboratory's (ARL) Electromagnetic Vulnerability Assessment
Facility (EMVAF), White Sands Missile Range (WSMR), NM. Participation included DOT’s federal partners/agencies (USCG, NASA,
NOAA, USGS, and FAA) and GPS manufacturers. Air Force/GPS Directorate conducted testing week of April 18th. 80 receivers were tested representing six categories of GPS/GNSS
receivers: General Aviation (non certified), General Location/Navigation,
High Precision & Networks, Timing, Space Based, and Cellular. Tests performed in the anechoic chamber include: Linearity (receivers CNR estimators are operating in the linear region)
- 1 MHz Bandpass Noise (Type 1)
- 1 MHz In-Band Noise (Type1)
- 10 MHz Long Term Evolution (LTE) (Type 2)
- Intermodulation (effects of 3rd order intermodulation).
The test results can be summarized as follows: 1 MHz AWGN and 10 MHz LTE interference signals ITM
bounds were produced for all emulated GNSS signals; most bounding ITMs showed little sensitivity to interference
signal types (AWGN (1 MHz) and LTE (10 MHz)); certified aviation receiver mask did not bound the masks of
the 6 civil receiver categories; and in-band interference 1-dB degradation levels were consistent
with expectation (-110 to -120 dBm/MHz for the L1C/A ITMs).
