A modular device, system and associated method, used to enhance the quality and output speed of any generic GPS engine is provided. The modular device comprises an inertial subsystem based on a solid state gyroscope having a plurality of accelerometers and a plurality of angular rate sensors designed to measure linear acceleration and rotation rates around a plurality of axes. The modular inertial device may be placed in the data stream between a standard GPS receiver and a guidance device to enhance the accuracy and increase the frequency of positional solutions. Thus, the modular inertial device accepts standard GPS NMEA input messages from the source GPS receiver, corrects and enhances the GPS data using computed internal roll and pitch information, and produces an improved, more accurate, NMEA format GPS output at preferably 2 times the positional solution rate using GPS alone. The positional solution frequency using the present invention may increase to as much as 5 times that...

MSK signal processing in a GPS correlator channel
Issued US US6160858
A method and apparatus for demodulating and decoding an MSK signal utilizing synchronous accumulation and simultaneous synchronization of reference carrier and MSK data clocks enables a GPS correlator channel in a multi-channel GPS receiver to be used for processing MSK signals. The PRN code epochs are synchronized with the MSK data clocks and the process of de-spreading with a PRN code is disabled in order to obtain coherent MSK demodulation without corrupting the MSK signal with a PRN code…

Irrigation positioning system
US US6512992
A means of accurately determining the position of a selected location such as at the end of a center-pivot irrigation system by using two Global Positioning System (GPS) receivers. The first GPS receiver is located at a fixed, known position such as at the center of the pivoting irrigation system while the second GPS receiver is located on a moving portion of the irrigation system. The first GPS receiver compares the GPS receiver reported position against the actual position and reports by wire…
A means of accurately determining the position of a selected location such as at the end of a center-pivot irrigation system by using two Global Positioning System (GPS) receivers. The first GPS receiver is located at a fixed, known position such as at the center of the pivoting irrigation system while the second GPS receiver is located on a moving portion of the irrigation system. The first GPS receiver compares the GPS receiver reported position against the actual position and reports by wire or radio link the position differences to the second GPS, where the differences are used to remove errors from the second receiver's measured position.

A system for generating a non-visual notification of a machine condition includes a machine condition sensor configured to sense a machine condition. A notification generation controller is in communication with the machine condition sensor. The notification generation controller generates a notification according to the sensed machine condition. In a feedback configuration the notification generation controller compares an integral of a rate of change of the sensed machine condition with a threshold to trigger the generation of a notification. In a guidance configuration the notification generation controller uses the deviation of the machine condition from a guidance direction determined with a steering algorithm to control the generation of a notification. A non-visual notification generator is in communication with the notification generation controller and generates a non-visual notification based on the notification.

The receiver was innovate as it combined DGPS and GPS receivers. The antenna was innovate as the first combined GPS and DGPS antenna, and even the DGPS receiver was an innovation as it provided fully automatic operating and included 3 processing channels with one specifically providing impulse noise processing, impulse noise was a major issue in these days.Other creatorsSee project -
DNAV-212 Software Package
Software package to control and monitor DNAV-212 receivers. This software also provided a nice solution for GIS data recording and performance measurements. It might not seem special today but back in the early days of GPS, manufactures did not supply software with their black boxes. Starlink supplied this package which made the GPS unit very useful out of the box. It was a DOS program!

GPS Inline Amplifiers
GPS inline amplifiers were used to extend antenna cables. These units were in high demand for use in cellular towers, timing systems, and GPS test during production. With Strarlink line-amp you could extend over the normal limit of 50 feet. We were surprised how well these devices sold. They were made in several gain and filtering versions.
