SCOUT has designed the KS-30 antenna to be tuned on the AIS frequencies. Perfectly suited to the AIS radar and AIS Engine. £ The AIS SART station should transmit Message 1 and Message 14 using the burst transmissions as described in Annex 9. The Messages 1 and 14 should use a user ID 970xxyyyy (where xx = manufacturer ID 01 to 99; yyyy = the sequence number 0000 to 9999) and Navigational Status 14 when active, and Navigational Status 15 when under test. AIS communication takes place using two VHF frequencies, 161.975 MHz and 162.025 MHz, using a bandwidth of 25 kHz. Although only one radio channel is necessary, each station transmits and receives over two radio channels to avoid interference problems, and to allow channels to be shifted among ships without loss of communication.

Because of the frequency used by the SART, (9.2 to 9.5 GHz) known as SHF or Super High Frequency, the Search and Rescue Transponder is considered to be a line of sight device much like the VHF radio. The antennas must be able to “see” each other to operate effectively.

The USCG has asked the Federal Communications Commission to authorize any US vessel to operate AIS on these two channels under its existing ship station license.

The plt.plot (or ax.plot) function will automatically set default x and y limits. If you wish to keep those limits, and just change the stepsize of the tick marks, then you could use ax.get_xlim () to discover what limits Matplotlib has already set. The default tick formatter should do a decent job rounding the tick values to a sensible number
