Abstract: An apparatus provides independent precise positioning for a reference station (10) having a GNSS antenna (12) for receiving a plurality of GNSS signals, and a GNSS receiver (14) for generating GNSS data based on the plurality of GNSS signals. The apparatus includes a positioning processor (50), a signal processor (52), and a signal transmitter (54). The positioning processor calculates a current position of the reference station based on the GNSS data without using position information of another reference station, and the reference station can be independently installed at a desirable location without surveying the desirable location. The signal processor generates error correction in a data format such as RTCM or CMR, where the error correction information includes the current position of the reference station. The GNSS data includes GNSS observation data and augmentation data obtained from the GNSS signals having centimeter-level augmentation information.

Abstract: In RTK positioning, a calibration memory stores calibration information for combinations of GNSS receivers. A memory processor retrieves the calibration information for a selected combination of a first GNSS receiver for a base station and a second GNSS receiver for a rover from the calibration memory. A calibration apparatus, by communicating with the rover and the memory processor, receives a first correction signal associated with the first GNSS receiver, obtains the calibration information and modifies the first correction signal therewith to generate a modified correction signal calibrated for the second GNSS receiver with respect to the first GNSS receiver, and transmits the modified correction signal to the rover. The rover performs the RTK positioning with respect to a known GNSS receiver of the base station using the modified correction signal, thereby automatically achieving the frequency-dependent hardware bias calibration for the second GNSS receiver with respect to the first GNSS receiver.

Abstract: The portable golf navigation apparatus includes a controller, a memory, a GPS/GNSS receiver, a display section, a wireless transceiver, a connector section for providing bi-directional communications, and a user input device for receiving user commands. The weighted golf course information includes names and position information of the golf course items and weight information associated with each of the golf course items. The controller calculates a current position of the apparatus based on the received GPS/GNSS signals, and calculates a distance from the current position to a golf course item based on the position information stored in the memory. The display section selectively displays, under control of the controller, the indication of the golf course item and, optionally, the calculated distance thereto with an emphasis such that strength of the emphasis is in accordance with the weight information associated with the golf course item.

Abstract: Authentication mechanism is provided to open service signals in Global Navigation Satellite Systems (GNSS), by inverting a plurality of bits in a pseudorandom noise code in a GNSS signal having a predetermined period of a binary bit sequence of N bits. A position of each inverted bit in the binary bit sequence is specified by a serial number generated for each period using a cryptographic pseudorandom number generator, where at least one of the position of the inverted bit and a number of the inverted bits in the period varies period by period. A decryption key is provided to a GNSS receiver, which correlates, using a corresponding cryptographic pseudorandom number generator, the received GNSS signal, and accumulates an amplitude thereof at the inverted bit, thereby determining if the received signal is counterfeit based on the ratio of the inverted bit amplitude with respect to the signal amplitude.

The positioning processor calculates a current position of the reference station based on received GNSS signals without using position information of another reference station, and thus the reference station can be independently installed at a desirable location without surveying or measuring the desirable location. The signal processer generates error correction information in a predetermined data format such as RTCM or CMR, based on the received GNSS signals, where the error correction information includes the current position of the reference station. The signal transmitter transmits the error correction information via a communication link, whereby rovers can perform centimeter-level RTK positioning using the error correction information from the reference station including the current position of the reference station.
