Alignment and Direction Control - True North is Tricky


Surveying Gyromat

The GYROMAT instrument series is a range of high precision surveying gyroscopes with band suspension, which are the result of more than 60-years of experience in the development and manufacture of gyroscopic measuring instruments. The fully automatic measuring procedure and measurement technique that have no preliminary orientation provide the greatest accuracy in determining direction in those areas in which other methods cannot be efficiently used, for example in mining and tunnelling.

The GYROMAT 3000 has for many years been a reliable instrument for measuring directions with an accuracy of 1/1000th gon, which corresponds to a deviation in arc of about 1.6 cm over a distance of one kilometre. The time needed for measuring a single direction is about 10 minutes. This time can be reduced by applying two other survey programs, but the measuring accuracy is also reduced. The option to add a theodolite or a total station as required enables the instrument to be used universally for geodetic applications or control work.

The GYROMAT 5000 is the latest product for high precision direction measurement with an accuracy of 0.8/1000th gon, which corresponds to a deviation in arc of about 1.2 cm over a distance of one kilometre. The time needed for measuring a single direction is only about 6 to 9 minutes. The new piezo drive with a high resolution angle encoder and the new energy concept with a reliable energy storage system and replaceable battery make the system faster, more reliable and easier to maintain. The option to add a theodolite or a total station as required enables the instrument to be used universally for geodetic applications or control work.
