In addition to the core autopilot and simulator products, H Scientific have developed a number of additional systems. A number of these are can be integrated with the autopilots, such as the flight termination system and power control system, while the GENIE system is mainly used with the simulator or with datalogging applications.
GENIE System (Analogue I/O to USB interface)
The GENIE board connects to the PC serial port or USB port, and therefore can be used equally with a laptop or desktop PC to provide external analogue and digital inputs and outputs. It can easily be daisy-chained to increase the volume of I/O if required.
Flight Termination System (FTS) or Remote Termination System (RTS)
The FTS is a fail-safe device which incorporates a relay which changes state when commanded. When the radio transmission is interrupted or becomes invalid for any reason, the FTS receiver switches off the relay. The relay can actuate a solenoid valve or other device to bring the vehicle into a safe condition.
Heading and Attitude Sensor (HAS-01)
The HAS-01 Heading and Attitude Sensor is a magnetic/inertial sensor designed to give heading, rate of turn, roll and pitch data.
Using a fast and accurate attitude sensor, together with sophisticated datafusion algorithms to provide a low-cost gyrostabilised motorised CCTV camera.
Logs data from different sources, e.g. received NMEA data from sensors, analogue, digital inputs / outputs from GENIE Interface Unit. The data can be displayed and logged.
Data logger software running on a Pico microprocessor. Ruggedised for sea and field trials.
Dual Redundant Power Control System
Allows two power supplies (e.g. batteries, alternators) to be connected to a single system and shares the load between them intelligently.
The rate gyro system makes use of datafusion algorithms that take rate gyro sensor information (providing an indication of rate-of-turn about the axis of interest) and fuse this with the primary sensor data (e.g. fluxgate compass for heading) to provide a more accurate angular reference.
Telemetry board offers analogue, digital and serial I/O. Serial communications with the base station software via a radio modem allows remote monitoring and control.
PHANTOM is a diver navigation system which comprises an on-board computer and a suite of sensors. It combines the data from the sensors to give a graphical and numerical display of the diver's position and progress through a pre-programmed mission, using electronic charts.
The modem controller simplifies communication with modems which require explicit control of the handshaking protocol.
COVELIA is an velocity sensor which measures the speed of a vehicle relative to the sea bed by measuring the displacement of the transducer over the time interval between two acoustic pulses.
