Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 103
10.2.7.2.
Battery Voltage
The battery reading appended is the battery under load reading in Volts made at the start of the
PREVIOUS environmental satellite transmission. The initial transmission will have append minus
one (-1.0). Example: “:YB 12.50” would be formatted if the voltage were 12.5.
10.2.7.3.
Lat/Long
This setting stands for Latitude/Longitude and it appends the geolocation of the station. This
information is provided by Satlink’s GPS module. Example: “:YL N39o1'15.00"W77o24'37.00"”.
Please note that the “ symbol is used in the example to indicate seconds.
10.2.7.1.
Tx fwd/ref power
This option provides the forward and reflected power readings of the PREVIOUS environmental
satellite transmission. The initial transmission will append minus one (-1.0). With a forward
power of 5W and a reflected power of 0.3W, Satlink would format “:YF 5.0 :YR 0.3”.
10.2.7.2.
Station Name
The station name option appends the customer entered Station Name setting. For Iridium
telemetry, this setting also controls whether the station name is included in the transmission
header.
If the station name were “Small Creek”, it would be formatted as “:YN Small Creek”
10.2.7.3.
Temp During Last Tx
This is the temperature recorded during the PREVIOUS environmental satellite transmission. It is
expressed in degrees Celsius. The initial transmission will append -1000.0. For a temperature of
25.53, Satlink will format “:YM 25.53C”
10.2.7.4.
Tx time
The time of the current transmission, expressed as HHMMSS. ":YD 131015" is used for a time of
13:10:15.
10.2.7.5.
Serial no
This is the serial number of station. The SHEF format would be “:SN 00001" where 00001 is the
station serial number.
10.2.7.1.
Tx Count
This option provides the count of good and bad transmissions. For a station that has made
19350 good and 2 bad transmissions, the SHEF format would be “:YG 19350 :YH 2”.
10.2.7.2.
Append Options Example
Here is an example of all the append options in a SHEF format using SEHF codes. The order of
the values is battery, lat/long, forward power, reflected power, station name, temperature, time
(HHMMSS), serial number, and transmission count:
:YB 11.99 :YL N45o27'28.47"W122o43'59.08" :YF 1.6 :YR 0.0 :YN Small
Creek :YM 25.53C :YD 172100 :SN 00001 :YG 19350 :YH 2
With SHEF codes disabled, the same append options look like so:
