By proactively staying at the leading edge of technology, Mayflower has been able to focus on low-cost miniaturized electronics applications, such as precision guided munitions.
In support of the U.S. Navy Guidance Integrated Fuze Program, Mayflower has embarked on an exciting miniaturization effort to reduce cost, volume, and power of a P(Y) code SAASM GPS Receiver with full Anti-Jam protection to support the demanding form factor and price point requirements of the program.
The program consists of the development and test of three custom ASICs as follows:
Integrity™ SAASM ASIC – the world’s smallest SAASM.
Beacon™ – a five channel RF down-converter ASIC for both L1 and L2 GPS frequencies. The device can support 1, 2, or 4 antennas in addition to a bypass channel. Each channel is independently powered, allowing channels to be powered down if not in use. The device includes an on-board VCO, synthesizer, 4+1 down-converter channel, AGC, and voltage regulation. The device is packaged in an extremely small 7 mm x 7 mm QFN package allowing it to fit and even the most space challenged applications.
Vanguard™ – an Anti-Jam System on Chip for the P(Y) and M code GPS signals. The Vanguard SOC supports various Mayflower developed Anti-Jam algorithms providing 30 dB of protection against multiple wide band jammers and 40 dB of protection against multiple narrow band jammers. The device is packaged in an 11 mm x 11mm low profile BGA package. The device provides a direct digital interface to the Mayflower GPS receiver chips (Integrity™ and Magic™ ) or can be followed by an RF up-converter and used as an Anti-Jam module in front of any third party GPS receiver.
All of the ASICs/SOC are designed to support the shock and balloting loads required for gun launched applications up to 20,000 Gs. With these devices, the guidance, navigation, and control sub-system of a guided munitions platform can be shrunk to very small volume. These devices can be used to create gun hard GNC printed circuit boards in almost any form factor to meet the demands of even the most advanced guided projectile programs.
The NavAssure® 100 receiver is one of the world’s smallest, lightest, and lowest power SAASM receiver*. Designed from the ground-up to service the most SWaP constrained applications, NavAssure® allows deployment of SAASM technology in platforms never thought possible. From embedded radios to artillery applications, to micro-UAVs and Blue Force Tracking applications, Mayflower’s micro SAASM receiver is redefining the military GPS receiver landscape. NavAssure® 100 is packaged in a 42 mm outside diameter form factor.
NavGuard® 100 is the smallest 4-channel Anti-Jam SAASM receiver designed for extreme size, weight and power (SWaP) constrained military GPS applications requiring SAASM and high anti-jam performance. At less than two cubic inches (42 mm diameter form factor) and using a fraction of the power required by other GPS and Anti-Jam systems, NavGuard® 100 makes totally secure GPS PNT possible for the most SWaP-constrained military applications. NavGuard® 100 also features an application processor for customer applications, such as GN&C, DI/UTC, and ES. NavGuard® 100 is suited for use in SWaP constrained precision guidance projectiles and mortars.
NavGuard® 400 is the smallest 4-channel Anti-Jam Electronics designed for extreme size, weight and power (SWaP) constrained military or civilian applications requiring high anti-jam performance. At less than two cubic inches (42 mm diameter form factor) and using a fraction of the power required by other anti-jam systems, NavGuard® 400 makes totally secure GPS PNT possible for the most SWaP-constrained military or civilian applications. NavGuard®400 also features an application processor for customer applications, such as GN&C, DI/UTC, and ES.
