Trimble SCS900 Hydrographic extensions

The concept of the Sonar extension to SCS900 is to enable the construction user to execute simple Hydrographic surveys using their SCS900 software together with existing positioning equipment, no need to learn another package or convert to new reporting facilities, the sonar effectively behaves as an extension to the existing survey detail pole for measuring water depth.

Trimble SCS900 Site Controller Software calculates position data in conjunction with the ATS Total Station, 5605 DR200+ Total Station, SPS700 Total Station, SPS780 and SPS880 Smart GPS Antennas, SPS750 and SPS850 Modular GPS Receivers, and SPS770 GPS Receiver. Developed by Trimble the SCS900 Extension SDK (software developers kit) enables software engineers to link third party sensors to the existing position data. The first system integrator to apply this link was Ohmex Instruments, a manufacturer of portable shallow water echo sounders for water depth measurement.

SCS900 Extension Module Drivers

A new feature of the SonarMite XP and PocketPC software are extension module interface drivers to the popular SCS900 construction software from Trimble. These drivers enable the user to interface a water depth measurement to the RTK position measurements within a machine control environment. Uses include many applications within the areas of marine and civil engineering.

New - SCS900 v2.5 features

	Time stamped data with integrated latency adjustment for depth correction algorithm
	Retention of Raw data values in data set to enable recalculation of depth data and QA values
	Updated Simulation mode to allow demonstration/testing of a SCS900 sonar system without the physical connection of an echo sounder device.
	Null mode to allow the SCS900 user to easily switch between modes with/without echo sounder.

The SonarMite instrument uses 'Smart' integrated echo sounder transducer technology, in addition to highly reliable bottom tracking algorithms using DSP techniques the system also outputs a quality value associated with every depth measurement made.
