Unmanned Hybrid Radio Frequency (RF) Remote Control (RC) and Autonomous waypoint following surface vessel (ASV)
Waypoint Navigation through the commercially available Ardupilot Series of Controllers, e.g. APM 2,5, 2.6, Pixhawk or Navio
Graphical mission planning and control software through a variety of open source packages for these controllers. Mission Planner, APM Planner and others
RC Control via commercial hobby grade 2.4 Mhz controllers and receivers, eg FRsky X9D transmitter and L9R receiver
Remote access to the navigation computers is possible vai a dedicated serial radio
Hull based on the Mokia ES-Kape impeller driven kayak with 3 piece modular design for easy transport
Subaru EX21 Electronic Start 7 HP 4 stroke engine
Dimensions 143” L, 36” wide, 19” tall, 195 lbs
6 G Tank, 4 to 28 hours depending on RPM
Maximum Speed 21 mph with 130 lbs load to 8 knots with 300 lbs load, based on no drag inducing sensors
Minimum cruising speed 3 knots with clutch, 1.5 knots with no clutch. Clutch enables zero speed, if no clutch zero speed is not possible unless engine is stopped.
Operating Conditions
Within Sight and RC Control Range of Operator
2 to 3 ft sea state, wind less than 20 knots. -10 deg C to 25 deg C tested temperature range
Sensor and Data Logging
A wide range of sensors are possible similar to a small boat (figure 1a)
Single beam recreational fishing grade echosounders are easily integrated (Data in Figure 2)
ADCPs in a sea chest are also a typical configuration
A Jetyak variant with a retractable keel to deploy a PingDSP swath bathymetric sidescan sonar was recently developed (Figure 1b)
Data logging is on a small fanless PC enclosed in water tight box. This can either Linux or Windows and
Data computer accessed by the operator via a long range wifi link allowing remote desktop display of data as it is acquired, and allowing real time adaption of sampling parameters.
