Non-GPS Projectile Navigation via Ultra Wideband Signals

"Multispectral Solutions, Inc. (MSSI) proposes to develop the Ultra WideBand (UWB) Radio Frequency (RF) components of a non-GPS navigation system. The complete non-GPS navigation system solution requires an integration of multiple technologies, rangingfrom small aircraft to real-time video/map correlation. Here, the scope is limited to propagation and timing of MSSI's UWB waveforms.The beneficial characteristics of MSSI's UWB nanosecond pulse waveforms are that they are spectrally confined, transmit data and allow for precision time of flight to measure distances between transmitters and receivers. Spectrally confined waveformsallow multiple RF systems to occupy the same platform without interference. Additionally, UWB waveforms offer a low probability of interception and detection (LPI/D), hence increasing survivability. Finally, the nearly all-digital nature of UWB hardwareallows for microminiaturization via ASIC and RF hybrid technology. These features make the non-GPS navigation UWB system applicable to many US Navy and Marine Corps geo-location applications.Under Phase I, two major objectives are proposed. The first objective will develop geo-location transmitters and receiver hardware in S-band (2-4 GHz). The second objective will support systems studies for non-GPS navigation. The proposed Phase I optionwill demonstrate the performance of differential time of arrival UWB geo-location hardware. Navigation with the accur
