Abstract

A GPS/GLONASS travel recorder which utilizes the accurate position and velocity information determinable from radio frequency signals emanating from GPS and/or GLONASS satellites and ground stations to create an accurate route map by joining the frequent accurate position data points with user selectable or automatically selected route symbology. Features of the route locality are automatically printed on a displayed map of the travelled route from prior stored legends that are designated with approximate position location, or can be inserted by a user with keyboard or mouse entry. The computer processor of the GPS/GLONASS travel recorder calculates distance traveled by the carrier, time of travel, height, and other user chosen parameters that are programmed into the processor. Such data are stored for later retrieval as is the route map.

Dependent claims

Carrier mounted apparatus for providing a precise real time trip record for a carrier by generating and displaying the trip record based on GPS/GLONASS receiver provided periodic precise position, velocity, and time data which comprises:

GPS/GLONASS signal receiving antenna system means;
a GPS/GLONASS signal processing receiver coupled to the antenna system means, for providing signals representative of the carrier's precise latitude and longitude position, precise height above mean sea level, precise time, precise north, east and vertical velocity components;
data storage media:
computer means having a display and coupled to said data storage media and to the receiver for processing the GPS/GLONASS position and velocity representative signals in real time in accordance with algorithm process instructions stored in the data storage media to provide real time travel route plots for viewing on the computer display;
the data storage media also for storing previously obtained signals representative of approximate or precisely known latitude and longitude described local map features of interest to a user in a latitude-longitude associative memory for real-time retrieval and display;
the data storage media also storing symbology generating instructions, and a vector processing program;
the data storage media also for storing spread sheet instructions, to compute accumulated trip mileage and accumulated trip business tax deduction;
the data storage media also providing for real time storage of GPS/GLONASS carrier position and velocity representative signals, and data resulting from processing by said algorithm process instructions, for later retrieval and display, and
printer means coupled to the computer means for providing, upon request, a hard copy of the travel route plots, the accumulated trip mileage and accumulated trip business tax deduction spread sheet from said spread sheet program instructions.

A method for providing a precise real time trip record for an object which includes the steps of:

receiving at the object radio signals from satellites of the GPS;
processing such radio signals to provide signals representative of the object's precise latitude and longitude position, the object's precise height above mean sea level, precise time, precise North, East, and vertical velocity components of the object;
processing the representative velocity and position signals to provide signals representative of a real time travel plot of the object;
providing a display showing real time travel plot of the object using said velocity and position signals;
computing accumulated travel route distance of the object, and accumulated travel mileage expense from said velocity and position signals;
obtaining, on the basis of precisely known latitude and longitude points on the travel route, local map features directly related to the latitude and longitude points on the travel route, the real time travel plot, and
displaying these local map features adjacent to the displayed travel plot of the object, and
producing a hard copy of accumulated trip mileage, accumulated trip business tax deductions and accumulated trip expense deduction spread sheet data tables using the computed accumulated travel route distance of the object and accumulated travel mileage expense.
