A DISTANCE MEASURING SYSTEM |
摘要 |
<p>A distance measuring system is disclosed in which a user (2) in possession of a portable distance calculator (50) can determine the distance (D1, D) between an actual position (B) and a fixed position (L, P). Satellite position data of the fixed position (L, P) is determined periodically and supplied to the calculator (50). The calculator (50) includes a satellite position receiver (51) and a processor (54) which permit the distance (D1, D) to be determined. In a preferred embodiment error correction is performed by determining a satellite differential position error at a known survey reference location (R) and supplying the error to the calculator (50) for correction of the actual position (B) and, where necessary, the fixed position (L, P).</p> |
