For more than a decade, Mayflower Communications has been a leader in developing advanced GPS receivers and GPS Radio Frequency Interference (RFI) mitigation - also referred to as "GPS protection" products. We have had Government sponsored research contracts awarded from NASA, DARPA, the U.S. Army, Air Force, Navy and DOT/FAA. Mayflower has combined this externally funded research with internal company funded R&D work to produce innovative GPS receivers, communication data links and patented RFI mitigation devices. In addition to our GPS receiver and mitigation products, we also offer powerful analysis and simulation software products expressly designed for analyzing and modeling wireless communication networks.

• Spread-Spectrum Data-Link

GPS Protection Products

• As the next generation of Mayflower GPS anti-jam devices, the AIC-2100 can suppress up to 50 dB of interference and jamming, from as many as 10 simultaneous pulsed, CW or narrowband interferers.
• The AIC-2100 is designed as a direct replacement for the AE-4 module, and works with both C/A and P(Y) code GPS receivers with FRPA antenna.

Key Features

• No Modification Required to Existing GPS System
• L1/L2 Under Receiver Control
• Totally Transparent to the Receiver (less than 1 DB)
• Real Time Jammer Suppression - less than 40 usec
• Up to 50 dB of Anti-Jam Processing Gain
• No Effect on Carrier Phase Measurement
• Accepts External Clock Reference
• IF Output (173.91 MHz) Available (as an option)
• Plug and Play
• Interference Alert Signal
• RS-422 and TTL Level Control Interfaces

• Based on Mayflower second generation patented anti-jam Adaptive Spatial Temporal Processing (ASTF) technology.
• Incorporates a 4-element antenna array and controls the antenna array pattern to direct nulls towards the RFI source while maximizing the desired signal-to-noise power ratio.
• Based on proven GPS anti-jam antenna technology developed by Mayflower for the U.S. Army CECOM, under the Small Affordable Anti-Jam GPS Antenna (SAAGA) Program.
• The SAAGA product has been tested on Black Hawk (UH-60) helicopter configurations of both active and passive antenna.

Key Features

• Employs digital antenna control technology as compared to the old analog RF antenna control.
• Permits cost and size reduction while preserving (and even enhancing) the performance features of the GPS anti-jam equipment.
• Packaged in an AE-4 foot print (overall dimensions: 9.1"Lx4.3" W, 5.0"H). The ACM-4000 has been flight tested and will mitigate multiple narrow-band, partial-band, as well as wide-band GPS jammer threat.
• Designed to operate with a 4-element GPS L1/L2 antenna array, therefore it will provide the desired anti-jam capability at L1 and L2 frequencies, under the control of the GPS receiver.
• Controlled via RS-232/422 through a connector (power connector) and can be powered externally.
• Uses a nominal 28 V power supply for vehicle operation.
• The ACM-4000 unit manages its power consumption, and can be easily configured to operate as an adaptive temporal filter (ATF) - minimum power consumption mode, an adaptive spatial filter (ASF), or as an adaptive spatial-temporal filter (ASTF) to mitigate effectively (with minimum power consumption) the GPS jamming threat. The ATF mode is effective in mitigating narrow band as well as partial band jammers.

• Based on Mayflower's third generation anti-jam technology developed for low-cost projectile applications.
• Incorporates a 4-element antenna array and controls the antenna array pattern to direct nulls towards the RFI source while maximizing the desired signal-to-noise power ratio.
• Based on proven GPS anti-jam antenna electronics packaging technology developed by Mayflower for the U.S. Navy (NAVSEA/NSWC) under the COTS Tactical Guidance UNIT (TGEU) Program.
• The ACM 500 product has been tested with different configurations of both active and passive antenna arrays and with multiple military GPS receivers under various jammer types spatially separated in elevation and azimuth.

Key Features

• Employs digital antenna control technology as compared to the old analog RF antenna control.
• Permits cost and size reduction while preserving (and even enhancing) the performance features of the GPS anti-jam equipment.
• Packaged on a single ~ 3-inch diameter PCB. The ACM-500 has been extensively tested and will mitigate multiple narrow-band, partial-band, as well as wide-band GPS jammer threat.
• Designed to operate with a 4-element GPS L1 antenna array.
• Tested to survive 8,000 Gs.
• The ACM-500 unit manages its power consumption, and can be easily configured to operate as an adaptive temporal filter (ATF) - minimum power consumption mode, an adaptive spatial filter (ASF), or as an adaptive spatial-temporal filter (ASTF) to mitigate effectively (with minimum power consumption) the GPS jamming threat. The ATF mode is effective in mitigating narrow band as well as partial band jammers.
