-========Garmin GPS16x HVS========
+========== 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.

-========RockBLOCK+ Iridium========
-| {{ :rockblock.pdf |RockBlock+}}      | RockBlock+ Brochure.|
-| https://www.rock7.com/products-rockblock-plus      | RockBlock+ Webpage.|
-The RockBLOCK device is IP68 rated and hosts an Iridium 9602 unit, an antenna and a voltage regulator. The 9602 unit is interfaced with RS-232 using AT commands. Depending on the conditions, the unit can send or receive a message approximately every 40 seconds. The cost is 0.1 to 0.05 GBP per 50-byte message, depending on the bundle that is bought. In addition, there is a 10 GBP line rental per month. The system has a limited bandwidth and is therefore only suitable for simple control monitoring or tracking applications. The maximum package sizes are 340 bytes for sending and 270 bytes for receiving. Although the latency is typically a few seconds, it may be as much as a minute or more.

-========433 MHz Radio Transceiver========
-The 433 MHz Radio Transceiver requires a 12 V input and is interfaced with RS-232 at TTL voltage levels. Device settings can be changed with a set of AT commands, but in operation, the device functions as a transparent serial link. This radio is employed for short-range communication with Level 1 during testing of its functionalities.

-========Owl VHF========

-The Owl VHF is a small, yet high performance radio transceiver packed with features. It's very flexible internal architecture allows a wide variety of modulation types and encoding. Rather than the typical SDR approach where samples are processed by an external device, the Owl does all its processing internally.	A large command set regarding modulation, encoding and user protocol is configured through a serial port.
