+========== Vector™ V104 GPS Smart Antenna ==========

-The Garmin GPS16x HVS (27) was selected as it is IPX7 rated and has a built-in antenna.
+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 device is interfaced with messages that follows the NMEA0183 protocol. Baud rate is not defined in the NMEA standard. The baud rate can be set to 4800, 9600, 19200 or 38400. Lower baud rate increases immunity against radio frequency interference (RFI) but requires more time for transfer. 38400 was selected and tested. The device follows RS-232 defined voltage levels but also supports TTL voltage levels. The device does not support polling but outputs the selected messages at a frequency of 1 Hz. The user can enable or disable the different available messages. The available NMEA-approved output sentences are: GPALM, GPGGA, GPGLL, GPGSA, GPGSV, GPRMC, GPVTG. In addition, the device can provide the following Garmin proprietary sentences: PGRMB, PGRME, PGRMF, PGRMM, PGRMT, and PGRMV. In order to be able to meet system requirement A.REQ.2.06.4, GPRMC is enabled. GPRMC provides SOG, COG, and position. The GPGGA message enabled in addition because it provides the following useful information: Signal quality, number of satellites with fix and horizontal accuracy of position.

+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.

-========== Garmin GPS 18x-5Hz LVC ==========

-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.

 ========== 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.
-{{:sentiboard.png?600|}}
+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.
