Title: Encoding system of picture signal
Inventor: FUKINUKI NORIHIKO
IPC: H04N1/41
Filed: 1985-08-07
Abstract: PURPOSE:To simply and efficiently encode plural picture elements by separating a picture signal to a block corresponding to adjacent plural picture elements and allotting a condition change between the block to a variable length code stipulated considering probability of the change. CONSTITUTION:Since a picture signal is high in self-correlation, the signal has high probability that it becomes the same pattern even in an adjacent next, namely, right block. Then, when change probability of patterns Xi and Xi+1 of the adjacent block is shown, Fig. 4 can be obtained. Namely, when linked probability (p) (Xi, Xi+1) of a condition Xi of the present block and a condition Xi+1 of the next block is shown, a place with high frequency and a place with low frequency exist as shown. Consequently, when a code word of a small number of bits is given to a place with high change probability (p) (Xi+1, Xi) and a long code word to a place with low change probability, the encoding can be executed by a small number of bits as a whole.

Abstract: PROBLEM TO BE SOLVED: To accommodate for elevation angle of an artificial satellite and meteorological condition changing momentarily by installing a line calculating part for finding a globe which has the specified distance as the radius and the position of the artificial satellite as the center. SOLUTION: A pseudo distance measuring part 11 measures distance between satellite - receiver, or pseudo distance calculated from the difference between sending time and receiving time by receiving a signal from the satellite. An orbit data collecting part 12 collects the orbit date of all satellites receiving, and a satellite position calculating part 13 calculates the position on the orbit of the satellite. A satellite position line calculating part 16 finds a globe having the distance based on time offset of pseudo distance outputted from a position measuring equation calculating part 15 as the radius and the position of the satellite as the center. A pseudo distance error calculating part 17 calculates the error of a line of the position of each satellite and least square estimated value of user position.  Since the variance of pseudo distance error is calculated for every position measurement, the variance of the pseudo distance error is obtained in real time, and a user moving at high speed can accurately conduct position measurement.
