The objective of this Army-funded program is to design and build a micro-MIMO radio that is energy-efficient, and to apply this technology to JTRS Cluster 5 and other Army tactical radios.

Mayflower’s MEADoWS (MIMO for Energy-Aware Distributed Mobile Wireless Systems) technology is an energy-efficient and spectrally-efficient Multi Input Multi Output (MIMO)-based radio. The MEADoWS system builds on Mayflower’s proven technology in MIMO antenna signal processing. The soldier’s requirements in future wireless mobile communication systems are very demanding on Size, Weight, and Power (SWAP); the power (energy) is the most critical of the three, as it often determines the size and weight. The proposed MEADoWS system innovations directly address this critical need for power reduction in soldiers’ radio by means of an energy-efficient MIMO physical layer, a cognitive MAC layer, and a collaborative network layer. The energy-efficient physical, MAC, and network layers of the MEADoWS system target different sources of energy consumption, leading to significant gains in energy-efficiency. The Phase I feasibility study demonstrated that MEADoWS meets the Army objectives of energy efficiency and applicability to JTRS Cluster 5. In the Phase II program, we will build a prototype MEADoWS and demonstrate its functionality in a test bed, with multiple MEADoWS units participating in the demonstration. In Phase III, we will transfer the MEADoWS technology to the General Dynamics (GD) JTRS Cluster 5 soldier radio.

In this era of untethered computing, wireless communications is ubiquitous: computers have Wi-Fi, consumer electronics have Bluetooth, and sensing and RF tracking technologies have Zigbee, to name just three of the numerous current and future wireless standards. This brings up two resource issues: (1) Spectrum (wireless spectrum is limited, so the devices need to be spectrally-efficient) (2) Energy (energy, provided by a battery, is limited, so the devices need to be energy-efficient). Our solution, based on MIMO, provides energy-efficient and spectrally-efficient communications. A military application of MEADoWS is the DoD JTRS Cluster 5 radio for the soldier.

Minneapolis, MN – May 11, 2004 – ATK’s (Alliant Techsystems, NYSE: ATK) Ballistic Trajectory Extended Range Munition (BTERM) II, an extension of the earlier Autonomous Naval Support Round (ANSR), captured the highly competitive award for development of the Navy five-inch Extended Range Munition (ERM). With a value of $30 million, the contract calls for ATK to perform a 16-month demonstration of an innovative extended range, low cost, gun launched projectile capable of operation in the Mk 45 Mod 4 and Mod 2 naval gun systems.

ATK’s teammates on ERM are The C.S. Draper Laboratory, Cambridge, Mass., Custom Analytical Engineering Systems (CAES), Cumberland, Md., and Mayflower Communications, Burlington, Mass.

ERM is ATK’s third advanced weapon development win in less than a year, following the earlier Advanced Anti-Radiation Guided Missile (AARGM) and Precision Guided Mortar Munition (PGMM) program awards. ATK’s fourth competitor for a precision systems prime award – the Mid Range Munition (MRM) – was successfully tested last month. That award decision is expected later this year.

ATK is a $2.3 billion advanced weapon and space systems company employing 13,200 people in 21 states. News and information can be found on the Internet at www.atk.com.

Burlington, MA – 07 August 2002 – Mayflower Communications Company, Inc., a technology leader in GPS and Communication Data Link technology, headquartered in Burlington, MA has been awarded a Small Business Innovation Research (SBIR) Phase II and III contract totaling $1.35 million from the Naval Surface Warfare Center, Dahlgren, VA. The Navy/DoD SBIR Program is a highly competitive and successful program. It funds R&D projects geared towards meeting DoD objectives at small technology companies, which also have the potential for commercialization in the private sector. The DoD SBIR program funded projects totaling $773 million in FY 2002.

The objective of this Navy/Mayflower SBIR project – Low-Cost High Anti-Jam GEU for Gun-Launched Projectiles – is to develop and deliver low-cost, high performance GPS anti-jam (A/J) modules and an inertial navigator suitable for use in guidance and control of a projectile using commercially available low-cost instruments such as micromachined silicon accelerometers. The program’s intent is to realize accurate navigation and guidance capability in the presence of GPS jamming at a much lower cost by integrating a set of components whose costs have been driven down by the competition resulting from high volume commercial applications. The outcome of this Phase II/III program will be a flight-qualified, low-cost GEU with enhanced GPS anti-jam (A/J) capability. This GEU will be suitable for use in gun-launched projectiles including Navy ANSR, ERGM, and Hyper Velocity projectiles, and Army Ex Caliber, and other PGMs. The low-cost tactical GPS/inertial guidance and navigation package could also be used in less demanding commercial applications including general aviation aircraft, automotive vehicles, farm vehicles and mobile robots.

Mayflower has enjoyed working with the U.S. Navy in enhancing the accuracy of Navy Precision Guided Munitions for over a decade. Our R&D work in advanced GPS navigation receiver, GPS anti-jam (A/J) electronics, and command data link for retargeting has been supported over the years by the Naval Research Laboratory (NRL), Office of Naval Research (ONR), NAVAIR (Patuxent River, China Lake and Pt. Mugu) and NAVSEA (Dahlgren Division) Command. “This proven Mayflower track record of successful R&D work for the Navy, as well as our ongoing R&D work for the US Army CECOM and AMCOM, has culminated in Mayflower being selected by the US Navy NAVSEA Command, Dahlgren Division to build and deliver the GPS anti-jam electronics module and the GPS/inertial navigation module for Navy Precision Guided Munitions, PGMs, such as the Navy ANSR projectile,” said Dr. Triveni Upadhyay, Founder and Chairman of Mayflower Communications Company.

Mayflower’s GPS navigation and anti-jam product, developed and delivered under this SBIR Program, will be integrated into the Navy ANSR projectile Tactical Guidance Electronics Unit (TGEU). The ANSR projectile, a fast spinning airframe, employs a novel navigation concept that uses accelerometers only (AO) instead of a full complement of accelerometers and gyros. This innovative AO concept was developed by Mr. John Fraysse at NAVSEA, Dahlgren Division for reducing the GEU cost of future Navy rolling PGMs. The Mayflower GPS anti-jam product, specifically developed for rolling ANSR airframe, is ideally suited for achieving the Navy cost reduction goal for the GEU. According to Fraysse, “Mayflower’s A/J concept was selected because it ‘raises the bar’ with respect to the present State-of-the-Art for small body projectiles and missiles and has general application to low-cost airframes being developed in the Navy and Army Tech Base programs.”

Mayflower Communications, a privately held company, is a leader in advancing radio navigation and communication technology with a strong focus on GPS anti-jam technology and its integration with other sensors, such as an inertial navigation sensor. Since the company’s inception in 1986, Mayflower has developed and patented advanced GPS anti-jam technologies and products, such as adaptive temporal filter (ATF), adaptive spatial filter (ASF) and combined adaptive spatial-temporal filter (ASTF) to mitigate both narrowband and wideband GPS jamming threats.

Naval Surface Warfare Center, Dahlgren Division (NSWCDD), under Naval Sea Systems Command (NAVSEA), is among the largest research and development (R&D) centers in the United States. The NSWCDD mission is to provide research, development, test and evaluation, engineering, and fleet support for surface warfare systems, surface ship combat systems, ordnance, mines, amphibious warfare systems, mine countermeasures, special warfare systems, and strategic systems.

Mayflower Communications will be exhibiting its technology and products at the 5th Annual Space and Missile Defense Conference and Exhibition in Huntsville, AL sponsored by the U.S. Army Space and Missile Defense Association and the National Defense Industrial Association-Tennessee Valley Chapter, and the Air Defense Artillery.
