TGT1 GOES Transmitter
11
TABLE 8.2-1 *# Parameter's Descriptions
Parameter Description
1 - 3 Set the transmitter's clock. All scheduled operations are refer-
enced to this clock. Because timing is critical, it must be set to
Coordinated Universal Time (CUT). CUT can be obtained by
calling the WWV or WWVH time services (call (303) 499-7111
for WWV time and (808) 335-4363 for WWVH). The clock
must be reset at least once a year. Parameter 1 is hours; 2 is
minutes and 3 is seconds. The TGT-1 clock is set and starts to
run when the “A” key is pressed after the 3
rd
parameter. Note:
This is a 24-hour format.
4 - 11 The NESDIS-assigned address. Convert the letters in the address
to their decimal equivalent (Table 8.2-2). For example when the
address is 0104C186, parameters 4 through 11 are the following:
Parameter Number User Types
04: 0 A
05: 1 A
06: 0 A
07: 4 A
08: 12 A
09: 1 A
10: 8 A
11: 6 A
12 NESDIS-assigned self-timed uplink channel (see Appendix E
channel/ frequency correlation). If not assigned a self-timed
channel, type in zeros.
13 NESDIS-assigned random uplink channel (see Appendix E for
channel/ frequency correlation). If not assigned a random
channel, type in zeros.
14 - 17 Self-timed transmission interval is NESDIS-assigned and usually
3 or 4 hours (minimum interval is 15 minutes). Parameter 14 is
days; 15 is hours; 16 is minutes and 17 is seconds. Note: This is
a 24-hour format.
18 - 20 Random transmission interval (the NESDIS-assigned time period
that the transmission is randomly re-peated, minimum interval is
5 minutes). Parameter 18 is hours; 19 is minutes and 20 is
seconds.
21 - 23 Set the time of the initial self-timed transmission (NESDIS-
assigned). The “initial” time is not the first time but an offset.
Self-timed transmissions occur on multiples of the self-timed
transmission interval plus the offset. Parameter 21 is hours; 22 is
minutes and 23 is seconds. Note: This is a 24-hour format.
