Handheld computers with gps capabilities are allowing contractors to create accurate construction records by linking notes to a precise location.

Topcon’s new GMS-2 system (below, left) has a built in camera, which also allows an image to be linked to the GPS coordinates, and the on-board compass adds direction details. The system has a built in GPS antenna, which can track both GPS and GLONASS satellites, and can also be used to collect GIS or survey data.

“On its own the GMS-2 can provide post-processed centimetre level accuracy or can be combined with an external GPS antenna to give millimetre accuracy,” said Mr Contino. “The system can also be connected to an on-site base station via bluetooth.”

The ProMark3 (below, right) from Magellan, formerly known as Thales, is also design to speed up on site collection of survey data and can provide centimetre accuracy. “We have focused on ease of use and the system is now available in several languages,” said Magellan marketing strategy senior director Stig Pedersen.
