Abstract
Information received by a calculating unit via a signal from a transmitting station to a receiving station is provided with a code, a number of integral multiples of the code coming into the receiving station during the signal transfer time that the signal requires to travel between the transmitting station and the receiving station. During a first iteration, the number of integral multiples of the code is calculated and the calculated number is used at least in a second iteration without a fresh calculation being carried out.
Claims17
A method for iterative determination of a distance between a receiving station and a transmitting station, comprising:
- receiving information by a calculating unit concerning a signal from the transmitting station that is received by the receiving station, the signal including a code which is received by the receiving station an integral number of times during a signal transfer time required for the signal to travel between the transmitting station and the receiving station;
- calculating, during a first iteration, the integral number of times the code is received;
- and
- using the integral number in at least a second iteration without recalculating.
A device for iterative determination of a distance between a receiving station and a transmitting station, comprising:
- an interface receiving information concerning a signal from the transmitting station that is received by the receiving station, the signal including a code which is received by the receiving station an integral number of times during a signal transfer time required for the signal to travel between the transmitting station and the receiving station;
- and
- a calculation unit calculating, during a first iteration, the integral number of times the code is received and using the integral number at least in a second iteration without recalculating.
A computer software product embodied on at least one computer-readable medium storing instructions to control a processor to perform a method comprising:
- receiving information by a calculating unit concerning a signal from the transmitting station that is received by the receiving station, the signal including a code which is received by the receiving station an integral number of times during a signal transfer time required for the signal to travel between the transmitting station and the receiving station;
- calculating, during a first iteration, the integral number of times the code is received;
- and
- using the integral number in at least a second iteration without recalculating.
