-The Garmin GPS 18x-5Hz LVC and the serial port on the BeagleBone operate on different voltage levels. Thus, MAX3232 voltage converter was used to convert the 5V signals of the GPS to 3.3V signals the BeagleBone serial port supports. The newly converted 3.3V signals are connected to the Rx and Tx pin headers of the UART1. To be able to receive the GPS data a GPS Task needs to be enabled in the same fashion as the AIS (Automatic Identification System). The IMC message GpsFix were then dispatched by the GPS Task and later consumed by the CAS Task. Here, the current GPS position (latitude, longitude), speed over ground and heading was set to be AutoNaut new system states.+Vector V104 GPS Smart Antenna offers superior navigation including accurate heading and position performance. V104 uses SBAS (WAAS, EGNOS, MSAS, etc.) for differential GPS position allowing Hemisphere GNSS to provide a low cost and highly effective heading and position based smart antenna. 
 + 
 +The rugged and low-profile enclosure combines Hemisphere GNSS’ Crescent® Vector technology and two multi-path resistant antennas for accuracy, portability and simple installation. The smart antenna, measuring less than a half meter in length, mounts easily to a flat surface or pole. The stability and maintenance-free design of V104 provides traditional GPS position and heading at a low cost, replacing the combination of low-accuracy GPS and fluxgate compass.

-The Model 120WX is Airmar’s solution for recreational boating; feature rich, in a durable, rugged, Small footprint that is IPX4 or IPX6 rated for this environment.+Reliable monitoring systems such as buoys, and USVs enable operational decision-making based on real-time, site-specific data rather than intuition. The highly changeable conditions at sea make offshore operations particularly challenging. Airmar has worked with many autonomous vehicle and buoy OEMs to develop the WeatherStation model 200WX-IPX7 that meets the operational challenges of this extremely harsh environment.
  
-Reliability and performance, along with no moving parts, makes the 120WX an easy and affordable choice for your recreational boating needs.+The low-power requirement of this patented model make it well suited for battery and solar powered applications. And the IPX7 housing is designed for this harsh and demanding environment.

 The ADIS16485 device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer using MEMS technology. The inertial measurement unit (IMU) is used on the AutoNaut for control and navigation applications. It provides accurate sensor measurements using dynamic compensation formulas from factory calibrations. SPI and register structure provide a simple interface for data collection and configuration control. It comes in a module that is approximately 47 mm × 44 mm × 14 mm and has a standard connector interface. The ADIS16485 device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer using MEMS technology.

-The Honeywell HMR3000 is a digital compass module that provides heading, pitch, and roll outputs for navigation. The three of Honeywell’s magneto-resistive sensors are oriented in orthogonal directions plus a fluid tilt sensor are employed to measure the vector components of the earth’s magnetic field and a gravitational reference. These solid-state sensors create a strapdown compass that is both rugged and reliable. The data output is serial full-duplex RS-232 or half-duplex RS-485 with 1200 to 19,200 data rates.+The Honeywell HMR3000 is a digital compass module that provides heading, pitch, and roll outputs for navigation.

 +========== SenTiBoard ==========
 +The SenTiBoard is a sensor timing board that accurately records when sensor messages are validated. To achieve high accuracy the SenTiBoard uses a 200 MHz microcontroller with a 100 MHz 32-bit internal clock, resulting in a resolution of 10 ns. The board uses the microcontroller's interrupt capture functionality, which registers the timestamp when a flank on a pin is detected, to register a sensor's reported Time of Validity (TOV) or Pulse Per Second (PPS). In addition, the time the first byte is transferred is also recorded, to support sensors that do not have dedicated TOV signals.
 +
 +Primarily, the SenTiBoard both communicates and is configured through the USB interface. This allows the board to be configured and tested on a standard computer on the operative system of choice, and then transferred to the on-board payload computer. If USB is not present on the on-board computer, other interfaces such as SPI or UART can be used, and sensor logging directly to an SD-card is planned. The SenTiBoard is designed to fit on top of the ODroid XU4 single board computer, with dimensions of 83 mm x 59 mm. To reduce the size further, the legs can be broken off, resulting in a board of 60 mm x 50 mm.
