Abstract
Abstract The present invention relates to a surveying method utilizing a GPS comprising steps of positioning an unknown GPS traverse station (TG) by said GPS with one GPS receiving means provided at a known reference station (B) and the other GPS receiving means provided together with a surveying equipment such as a total station at said unknown GPS traverse station (TG), both of these stations (TG, B) being to be interferometrically measured utilizing said GPS; and surveying unknown stations (H1, H2, H3) surrounding the GPS traverse (TG) station, with a target such as a prism being provided at a known reference direction station (B) which can be clearly viewed from said surveying equipment provided at said GPS traverse station (TG). The invention relates also to a surveying equipment comprising one GPS receiving means provided at a known reference station (B) and the other GPS receiving means associated with an unknown traverse station (TG), said other GPS receiving means being incorporated in the surveying equipment such as a total station and both of these stations being to be interferometrically measured utilizing the GPS.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
A surveying method utilizing a GPS (grobal positioning system), said surveying method comprising steps of positioning an unknown GPS traverse station by said GPS with one GPS receiving means provided at a known reference station and the other GPS receiving means provided together with a surveying equipment such as a total station at said unknown GPS traverse station, both of these stations being to be interferometrically measured utilizing said GPS; and surveying unknown stations surrounding the GPS traverse station with a target such as a prism being provided at a known reference direction station which can be clearly viewed from said surveying equipment provided at said GPS traverse station.
Claim 2
Dependent Claim
109 words
A surveying method utilizing a GPS, said surveying method comprising steps of positioning an unknown GPS reference direction station by said GPS with one GPS receiving means provided at a known reference station and the other GPS receiving means provided together with a target such as a prism at said unknown GPS reference direction station, both of these stations being to be interferometrically measured utilizing said GPS; and surveying unknown stations presenting good visibility and surrounding a surveying equipment such as a total station by said surveying equipment provided at a known station which can be clearly viewed from the target set up at said GPS reference direction station.
Claim 3
Dependent Claim
113 words
A surveying method utilizing a GPS, said surveying method comprising steps of positioning a GPS traverse station and a GPS reference direction station by the GPS with one GPS receiving means provided at a known reference station and the other GPS receiving means provided at said unknown GPS traverse station and GPS reference direction station both of which are to be interferometrically measured utilizing said GPS and which can be clearly viewed from each other; and surveying unknown stations presenting good visibility and surrounding a surveying equipment provided at said GPS traverse station such as a total station, with a target such as a prism being provided at said GPS reference direction station.
Claim 4
Dependent Claim
50 words
A surveying method as recited in claim 1, 2 or 3, wherein the relative position of the stations presenting good visibility to each other and having been interferometrically measured by the GPS is surveyed by the surveying equipment such as the total station to check the result of positioning procedure.
Claim 5
Dependent Claim
52 words
A surveying method as recited in claim 1, 2 or 3, wherein the relative positions of respective pairs of traverse stations which have been successively surveyed by the surveying equipment such as the total station during the traverse surveying are interferometrically positioned utilizing the GPS to check the result of surveying procedure.
Claim 6
Dependent Claim
52 words
A surveying epuipment comprising one GPS receiving means provided at a known reference station and the other GPS receiving means associated with an unknown traverse station, said other GPS receiving means being incorporated in the surveying equipment such as a total station, both of these stations being interferometrically measured utilizing the GPS.
Claim 7
Dependent Claim
27 words
A surveying equipment as recited in Claim 6, wherein the GPS receiving means incorporated in the surveying equipment such as the total station comprises a GPS antenna.
Claim 8
Dependent Claim
32 words
A surveying equipment as recited in Claim 6, wherein the GPS receiving means incorporated in the surveying equipment such as the total station comprises the GPS antenna provided integrally with a receiver.
Claim 9
Dependent Claim
32 words
A surveying equipment as recited in Claim 6, 7 or 8, wherein the GPS receiving means is mounted on the surveying equipment such as the total station by a disconnectable connector mechanism.
Claim 10
Dependent Claim
51 words
A surveying equipment as recited in Claim 6, 7, 8 or 9, wherein the GPS receiving means is mounted on the surveying equipment so that a mechanical or electrical centre of said GPS receiving means be positioned on a mechanically vertical axis of said surveying equipment such as the total station.
Claim 11
Dependent Claim
48 words
A surveying target comprising one GPS receiving means provided at a known reference station and the other GPS receiving means associated with an unknown reference direction station being incorporated in the surveying target such as a prism target, both of these stations being interferometrically measured utilizing the GPS.
Claim 12
Dependent Claim
22 words
