
<CRLF> is a carriage return, line feed

IDIDIDID is the eight-byte hexadecimal satellite ID

JJJ is a three digit Julian Day, which is the number of days of the year. January 1st is Julian Day
one, and February 1st is Julian Day 32. This number is always three digits (0 padded)

HHMMSS are the hours minutes and seconds. This is the time of the scheduled transmission. It is
always 6 bytes (0 padded).

Meas1_Data()..MeasN_Data are the data from the active measurements included in the
transmission.

Measurement data is always four digits followed by a space (0 padded).

All values are multiplied by a 100.

No decimal point is used for measurement data.

Range of transmitted data is 0 to 9999 (numbers out of range are transmitted as 0000 or 9999).
This means that the sensor data should be between 0 and 99.99 before formatting.
If the user elects to append battery voltage, one of the two will be appended:

Two lines of battery voltage information will be added. Both lines take the same format:
“12.5<CR><LF>” (three digits of battery voltage and a decimal point). The first line is the battery
voltage prior to this transmission. The second line is the battery voltage during the last
transmission.
This is an example transmission:
010570F2 108183053
0250 0250 0250 0250
2231 2232 2233 2234
12.2
12.1

On the first line 010570F2 represents the hexadecimal satellite ID. 108 is the Julian Day (for the
year 2005, that is April 18th). 183053 means 18 hours 30 minutes and 53 seconds.

The second line (0250 0250 0250 0250) shows four readings of the first sensor. This measurement
had four same readings. Before formatting, that reading was 2.50. It was multiplied by 100 and
padded with a leading zero.

The third line (2231 2232 2233 2234) shows four different readings of the second sensor. That
sensor’s readings were originally 22 .31, 22.32, 22.33, and 22.34 respectively. They were
multiplied by 100 and padded with a leading zero.

The fourth line (12.2) is the battery reading in Volts prior to transmission.

The last line (12.1) is the battery reading in Volts during the last transmission.
