Miniaturized Radio Frequency Sensor Masthead

The Mini-RF instruments aboard two lunar orbiting missions will search for lunar ice and help create accurate 3-D lunar relief maps.

Under contract to the U.S. Navy, Raytheon provided miniaturized-radio frequency (Mini-RF) antennas, RF electronics and flight software for two instruments: one for NASA’s Lunar Reconnaissance Orbiter (LRO), and another, known as Mini-SAR, for the Indian Space Research Organisation’s (ISRO) Chandrayaan-1 spacecraft.

Mini-RF technology will help to establish whether exploitable quantities of water ice exist at the lunar poles and provide surface imaging used to characterize topography in preparation for future manned missions to the moon.

Built in 18 months, under a tightly constrained budget, Raytheon’s miniaturized-radio frequency technology stands ready to meet urgent civil and military space needs.
