Products - Instrumentation and Interface Systems

H Scientific have developed the following navigational instruments, instrumentation and interface cards:

COVELIA - A sonar correlation velocity log which enables AUVs and other submersibles to navigate as accurately as possible without recourse to position fixing sensors such as GPS. The CVL may replace the widely-used Doppler Velocity Log in many applications,
Rate gyro board - The use of rate gyros improves the accuracy of primary source data including heading, roll and pitch. We have developed a data fusion method which extracts the complementary strengths of the rate gyro and the fluxgate compass, whilst discarding their respective weaknesses, which provides both rate and heading information which is optimally filtered for the purpose of the autopilot. The datafusion algorithms are incorporated into a PCB together with 3 rate gyro aligned to give pitch, roll and yaw rates.
Data telemetry board - A telemetry system has been developed which allows the user to remotely monitor instrumentation. This includes digital, analogue and serial digital I / O combined with a proprietary efficient and robust communications protocol.
GENIE 1 and GENIE 2 modules - H Scientific have developed a family of multiple channel analogue/digital I/O boards. The GENIE boards connect to the PC serial port or to a USB port and therefore can be used equally with a laptop or desktop PC to provide external analogue and digital inputs and outputs. Multiple boards can be daisy-chained to increase I/O. There are two variants of the GENIE board: the GENIE 1 provides specialist features in addition to analogue/digital I/O while the GENIE 2 is a general purpose board with multiple high resolution analogue I/O and digital I/O channels.
Modem controller - H Scientific have developed a module which explicitly handles the handshaking between modems. This reduces the complexity of working with modems which require hardware handshaking.
