Abstract:
A method of augmenting a mobile radio positioning system (Mobile_RADPS) by using a stationary fan laser transmitter. A rover comprises the mobile radio positioning system (Mobile_RADPS) integrated with a mobile laser detector. The stationary fan laser transmitter is integrated with a stationary radio positioning system (Stationary_RADPS). The method comprises the following steps: (A)generating a single sloping fan beam by the stationary fan laser transmitter; (B) detecting the single sloping fan beam generated by the stationary fan laser transmitter by using the mobile laser detector; and (C) timing the fan laser beam strike at the rover's location and using the timing of the fan laser beam strike at the rover's location to improve an accuracy in determination of position coordinates of the rover.
Abstract:
A combined satellite positioning and electro-optical total station system includes a reference oscillator that provides local oscillator signals for a satellite navigation receiver and a precision frequency source for use by an electronic distance meter. When the satellite navigation receiver is locked onto and tracking orbiting navigation satellites, the highly precise cesium-rubidium clocks in the navigation satellite system can be used as standards to control the reference oscillator in the combined satellite positioning and electro-optical total station system. Baseline measurements made by the electronic distance meter are therefore not subject to mis-calibrations and drift as long as the satellite navigation receiver is locked onto and tracking the orbiting navigation satellites.

Abstract:
A system embodiment of the present invention comprises a fixed and a roving pair of four-observable GPS receivers and a communication link between them for double differencing code and carrier measurements. Carrier phase integer ambiguities are resolved efficiently by searching the simultaneous narrow-lane intersections of both the L1 and L2 wave fronts propagated by the GPS satellites being tracked. External constraint information, such as elevation, is additionally used to speed up integer ambiguity resolution. Data between the reference station and the rover is communicated in compressed form at a regular interval, e.g., once a second at each epoch, and demi-measurements of carrier phase are obtained more frequently, e.g., ten times a second, and used to propagate solutions between epochs.
Abstract:
A surveyor range pole, for example, equipped with a GPS receiver and antenna mounted at the top end, a battery mounted at the bottom end to better balance the pole, a tilt sensor and a direction sensor. The tilt sensor and direction sensor provide information about the vector that lies between the top and the bottom points of the range pole. The GPS receiver computes the position of the top end of the range pole from GPS satellite signals received by the GPS at the top end, and then computes the position of the bottom end of the range pole with the vector information. A variable length, telescoping range pole includes a linear transducer for automatically measuring the overall length of the range pole and contributing that length information to the vector calculation.
Abstract:
A sexual stimulation device comprises a casing (2) in which is contained a vibrator unit and connection means in the form of gripping limbs (6, 7) for holding the device to the penis. The connection means extend about the penis in a connection place (P) and a longitudinal axis (c) of the casing (2) is inclined to the connection plane (P) whereby, in use, the casing (2) extends along and away from the penis.
Abstract:
In a method for refining a position estimate of a low earth orbiting (LEO) satellite a first position estimate of a LEO satellite is obtained with a GNSS receiver on-board the LEO satellite. The first position estimate is communicated to a Virtual Reference Station (VRS) processor. VRS corrections are received at the LEO satellite, the VRS corrections having been calculated for the first position estimate by the VRS processor. The VRS corrections are processed on-board the LEO satellite such that a VRS corrected LEO satellite position estimate of the LEO satellite is generated for the first position estimate.
