Abstract
A method for determining an elevation of a laser detector assembly includes calculating an estimated elevation of a laser detector assembly based on data from an inertial measurement unit and a detected laser strike. The estimated elevation is then output. A detected elevation of the laser detector assembly is calculated based on the detected laser strike and the detected elevation is output in response to the detected laser strike. The estimated elevation is calculated and output between outputs of detected elevations.

A method comprising:
- calculating an estimated elevation of a laser detector assembly comprising a plurality of laser detector elements, the calculating based on:
- 1) data received from an inertial measurement unit comprising at least one accelerometer and at least one gyroscope;
- and
- 2) a detected laser strike detected at one of the plurality of laser detector elements of the laser detector assembly;
- and
- outputting the estimated elevation.
An apparatus comprising:
- a plurality of laser detector elements;
- an inertial measurement unit comprising at least one accelerometer and at least one gyroscope;
- a memory storing computer program instructions;
- and
- a processor communicatively coupled to the memory, the plurality of laser detector elements, and the inertial measurement unit, the processor configured to execute the computer program instructions, which, when executed on the processor, cause the processor to perform operations comprising:
- calculating an estimated elevation of a laser detector assembly comprising the plurality of laser detector elements, the calculating based on:
- 1) Data received from the inertial measurement unit;
- and
- 2) a detected laser strike detected at one of the plurality of laser detector elements of the laser detector assembly;
- and
- outputting the estimated elevation.
A non-transitory computer readable medium storing computer program instructions, which, when executed on a processor, cause the processor to perform operations comprising:
- calculating an estimated elevation of a laser detector assembly comprising a plurality of laser detector elements, the calculating based on:
- 1) data received from an inertial measurement unit comprising at least one accelerometer and at least one gyroscope;
- and
- 2) a detected laser strike detected at one of the plurality of laser detector elements of the laser detector assembly;
- and
- outputting the estimated elevation.
