Abstract

Determining positions for a set of points using a GNSS rover unit includes receiving a correction signal from a GNSS base unit. The GNSS base unit is located at a fixed point. The correction signal is used to determine a position of a point of the set of points. The position is stored in memory of the GNSS rover unit as position data. These steps are repeated for each point in the set of points. Raw GNSS data of the GNSS base unit is transmitted to the server system. A corrected position of the GNSS base unit is received from the server system. The position data is translated based on the corrected position of the GNSS base unit to produce adjusted position data.

Claims

1. A method for determining positions for a set of points using a GNSS rover unit, the method comprising:

(a) receiving a correction signal from a GNSS base unit, wherein the GNSS base unit is located at a fixed point;

(b) using the correction signal to determine a position of a point of the set of points;

(c) storing the position in memory of the GNSS rover unit as position data;

(d) repeating steps (a)-(c) for each point in the set of points;

(e) transmitting raw GNSS data of the GNSS base unit to a server system;

(f) receiving, from the server system, a corrected position of the GNSS base unit based on the raw GNSS data;

(g) translating the position data based on the corrected position of the GNSS base unit to produce adjusted position data.

2. The method of claim 1 further comprising:

(h) receiving the raw GNSS data of the GNSS base unit at the GNSS rover unit, wherein the transmitting raw GNSS data of the GNSS base unit to the server system is performed by the GNSS rover unit.

3. The method of claim 1 further comprising:

(i) verifying a position of the GNSS base unit with the corrected position of the GNSS base unit.

4. The method of claim 1, wherein steps (e)-(g) are done automatically in response to a user command.

5. The method of claim 1, wherein steps (e)-(h) are done automatically in response to a user command.

6. The method of claim 1, wherein the correction signal is received at the GNSS rover unit over a first wireless interface.

7. The method of claim 6, wherein the raw GNSS data of the GNSS base unit is received at the GNSS rover unit over a second wireless interface different from the first wireless interface.

8. The method of claim 7, wherein the raw GNSS data of the GNSS base unit is transmitted to the server system over a third wireless interface.

9. The method of claim 6, wherein the raw GNSS data of the GNSS base unit is received at the GNSS rover unit over a second wireless interface different than the first wireless interface.

10. The method of claim 6, wherein the raw GNSS data of the GNSS base unit is transmitted to the server system over a third wireless interface different than the first wireless interface.

11. The method of claim 1 further comprising:

(j) receiving the position of the GNSS base unit from a user.

12. A non-transitory computer-readable storage medium storing computer executable instructions for:

(a) receiving a correction signal from a GNSS base unit, wherein the GNSS base unit is located at a fixed point;

(b) using the correction signal to determine a position of a point of the set of points;

(c) storing the position in memory of the GNSS rover unit as position data;

(d) repeating steps (a)-(c) for each point in the set of points;

(e) transmitting raw GNSS data of the GNSS base unit to a server system;

(f) receiving a corrected position of the GNSS base unit from the server system;

(g) translating the position data based on the corrected position of the GNSS base unit to produce adjusted position data.
