<li><strong>Messages</strong> is the number of messages received by the UAT (978 MHz) and 1090 MHz radios. "Current" is the 60-second rolling total for each receiver; "Peak" is the maximum 60-second total. The 1090 total includes all 1090 MHz Mode S messages received, including all-call and TCAS interrogations that do not carry ADS-B position information. If a UAT radio is receiving uplinks from one or more ground-based transceivers (GBT), this will be indicated under <strong>UAT Towers</strong>, with more details available on the Towers page.</li>
<li><strong>GPS</strong> indicates the connection status of any attached GPS receivers. Reported data includes the type of position solution, the number of satellites used in that solution, the number of satellites being received, and the number of satellites tracked in the GPS almanac data. Position and accuracy details can be viewed on the <strong>GPS/AHRS</strong> page.</li>
<p>Additional statistics include the number of detected software-defined radios (SDRs), number of current DHCP network clients, uptime, temperature of the Raspberry Pi CPU, and the current clock settings on both the Raspberry Pi and the device / browser used to view this page.</p>
