Message Format
B-2 Transponder T95 Messages
The following is the method of evaluating the maximum transmission time for the
T95:
Number of bytes per message: TXBytes = SC + UD + CRC + Flag + Key
Number of bits per byte: BitsPerByte = 12 for DR4, and = 11 for DR3
Number of bits per message: TXBits = Sync + BitsPerByte*TXBytes
Bit duration: BitLen = 1/DR
Message length: MsLen = 0.0007 +TXBit*BitLen
Intermessage constant: InterMsgUnit = (UD + Flag)*0.0003066, for DR4;
= (UD + Flag)*0.0005657), for DR3
Intermessage delay: InterMsgDelay = [SD +RND(0…31)]*InterMsgUnit;
(RND - random value)
Maximum number of transmitted messages: NM = IP +RC; if LT = N
Total transmission time: TXTime = NM (MsLen +(NM-1) (InterMsgDelay)

transmitted in five seconds, using different sets of parameters for the T95.
