Definitions
- This invention relates generally to an apparatus, system and method for transmitting Global Positioning System (GPS) signals over multimode fiber.
- GPS Global Positioning System
- VCSEL Vertical Cavity Surface Emitting Laser
- multimode fiber comprises a bandwidth specified at less than 1GHz. Therefore, multimode fiber appears unsuitable for GPS signals which currently comprise L1 (1575.42MHz) and L2 (1227.6MHz) frequencies over long-range distances of up to 2000 feet and more. Because the multimode fiber bandwidth is specified for digital data, comprised of 1 's and O's, and the multimode fiber comprises different modulation frequencies, the waveforms would likely be distorted with increased fiber length. These factors, inter alia, combine to render multimode fiber unobvious choice for GPS signal transmission.
- a method for transmitting GPS signals over multimode fiber comprising: providing a GPS antenna having a specified gain; providing a fiber optic transmitter comprising a VCSEL multimode transmitter having a specified noise level and operatively connecting the GPS antenna with the fiber optic transmitter; providing an amplifier comprising a specifiable gain in the fiber optic transmitter; ensuring the total gain comprising the GPS antenna gain plus the specified amplifier gain is greater than the VCSEL multimode transmitter's noise level; connecting the fiber optic transmitter with a fiber optic receiver with a length of multimode fiber; operatively connecting the fiber optic receiver with at least one GPS receiver; receiving GPS signals with the GPS antenna; transmitting the GPS signals from the GPS antenna to the fiber optic transmitter; amplifying the GPS signals to the specified gain; transmitting the amplified GPS signals to the fiber optic receiver; and transmitting the amplified GPS signals to the at least one GPS receiver.
