1. All in one dual antenna unit, cab mounted GPS smart-antenna comprised of the following components: a primary and secondary GPS antenna with high accuracy tilt sensor, dedicated gyro, separate UHF antenna, GPS receiver motherboard, and vibrationdampening, temperature resistant foam surrounding the internal components of the smart-antenna. 2. Antenna will be enclosed in a ruggedized polymer shell above, with a sturdy metal cradle below; a metal frame using rare earth magnets to affix the smart-antenna to the roof of the heavy equipment is required. A simple metal housing (box or otherwise) design housing the antenna, high accuracy slope sensor or any other component for this project is unacceptable. 3. The external, cab mounted smart-antenna must include the following standards for water ingress, shock and vibration: IP69, MIL-STD81 0G, MIL-STD-202F, and IEC 60068-2.
