Omnitech designed the PROMS to provide measurements of depth, acceleration (X-Y-Z), pitch and roll angles, and ambient water temperature for a towed submersible SONAR body. The main engineering challenge was to design the data acquisition system so it could communicate reliably using a single un-sheilded, un-twisted pair of wires bundled with conductors carrying 50 kW electrical pulses to the SONAR body. Induced voltages in the 2000 foot long communications pair exceeded 300V, with current surges to 8 amps. Omnitech's solution was powered, and communicated, through one pair while providing error free array environmental data at 40 samples/second.

Omnitech worked as part of a team to design a thermal manikin capable of responding to sudden environmental temperature changes. Omnitech designed the distributed data acquisition system to measure 30 temperature and 40 heat flow sensors distributed throughout the manikin. The hardware was also capable of controlling and measuring the power of 30 distributed heaters. All data was transmitted to a PC via a serial link, where it was recorded and displayed using a custom designed LabWindows/CVI application.

Our customer needed to remotely monitor the performance of (16) RF Power Amplifiers operating in the HF to UHF range. Omnitech's solution consisted of a custom designed data acquisition system and PC based LabVIEW application. The data acquisition hardware - located in a remote transmitter shed - utilized a 486 SBC programmed in C, (2) 16-channel high-speed ADCs and (32) power sensing elements. A fiber-optic link connected the data acquisition hardware to a PC in the main operations building. The LabVIEW application allowed the customer to monitor transmitter forward and reflected average power, forward and reflected PEP, return loss, VSWR and percent modulation of one, or all 16 RF power amplifiers.

Omnitech was contracted to design a portable ship tracking system to precisely record the position of ships during acoustic and magnetic signature measurements. The shipboard hardware consisted of two custom designed DGPS receivers located at the ships bow and stern, a UHF data link and a control/display unit using the Z-World Rabbit 2000 controller. Shore based hardware consisted of a custom designed UHF data link and DGPS reference station with coded time-stamp output to synchronize data collection hardware. Shipboard software was developed in Dynamic C and shore based software was developed in LabVIEW. The LabVIEW software graphically and numerically displays the ship's position relative to the position of fixed under-water hydrophones and magnetic sensors. The software also distributes ship's position via LAN to a variety of other custom developed LabVIEW applications for data analysis and logging.
