Description:

With over 10 years of experience in high-precision receiver design, Magellan has developed an OEM GPS and GPS+GLONASS receiver explicitly for the aviation industry. While many previous designs have been successful with aircraft and aircraft systems manufacturers for test flight applications, the Ashtech® GG12 from Magellan is ideally suited for integration within Technical Standard Order (TSO) Flight Management Systems (FMS), ground-based reference stations for GPS aircraft landing systems (SCAT I and LAAS) and other avionics. In addition to traditional GPS receiver design and ISO 9001 engineering practices, the GG12 design team has adhered to all FAA/RTCA design criteria.

Certification
The GG12 software has been developed in accordance with the requirements for RTCA DO-178B Level B (Software Considerations in Airborne Systems and Equipment Certification). The hardware has been developed to conform to the RTCA DO-208 (MOPS for Airborne Supplemental Navigation Equipment Using GPS) requirements. The hardware and navigational accuracy has been developed in accordance with the RTCA DO-217 (MASPS DGNSS Instrument Approach System: SCAT-I) requirements.
The receiver capably operates in autonomous or differential mode, making it ideal for all phases of flight, including precision approach. It also provides code and carrier data for ground reference station operation.

Anti-jamming
The GG12 receiver features extensive anti-jamming capabilities in the RF hardware.

GPS-only configuration
The GG12 GPS board incorporates all-in-view tracking of up to 12 satellites with a loss of lock re-acquisition time of less than 3 seconds, and meets the Continuous Wave Interference (CWI) specification from RTCA DO-208 and DO-229 (WAAS, MOPS).

GPS+GLONASS configuration
The GPS and GLONASS RF sections are independent, so that in-band CWI jamming on GLONASS frequencies will not affect GPS, and vice-versa. The GPS component of the receiver meets the CWI specification from RTCA DO-208 and DO-229. The GLONASS portion of the receiver satisfies a similar CWI specification. Both the GPS and GLONASS receiver portions meet DO-235 requirements for resisting RF interference to satellite signals, providing superior accuracy and reliability.

Each channel can be dynamically assigned to GPS or GLONASS. You may specify which channels track which system, or the receiver can perform this task automatically. In automatic mode, you may define a primary system, wherein the receiver tracks as many satellites of the primary system as possible, and uses the remaining channels to track satellites from the secondary system. The GPS+GLONASS receiver can be configured as a GPS-only receiver, or a GLONASS-only receiver.

Evaluation Software
Evaluate software is available with the GG12 and provides visual displays of satellite information, receiver position and velocity, as well as data logging and analysis. It also allows direct communication with the receiver.
Compatible with all Ashtech receivers, the software runs on Windows version 3.x Windows 95/98 and Windows NT platforms.

Accuracy and TTFF specs.based on tests conducted in California. Differential tests performed using Ashtech Z-Sensor ™ base station with Geodetic antenna and GG12 GPS Board remote with Geodetic antenna (Marine IV antenna for TTFF). Antenna benchmark locations determined using CORS sites Point Blunt (PBL1)and Pigeon Point (PPT1). Tests at different locations under different conditions may produce different results.

Position accuracy specifications are for horizontal positioning. Vertical error is typically <2 times horizontal error.

Real-time position accuracies obtained with SA off. With SA on, accuracy of autonomous positioning may degrade up to 100 meters (95%)as specified by the U.S.Department of Defense.
