+The data type specifier is used to compute the CRC, along with the payload. Only format for SMS and TLE have been specified.
 
 \subsection{SMS}
 
 SMS is a way to send a null terminated UTF-8 text message quickly and efficiently. With a maximum of 33 data frames and 25 bytes per data frame, a 1-byte identifier, \texttt{0x05}, and a 2-byte CRC, the maximum number of characters in an SMS message sent via Packet Mode is $(33 \times 25) - 4$, or, $821$ bytes. The SMS message should not have any interspersed null bytes and should not contain any control characters expect for tab (\texttt{0x09}) and newline (\texttt{0x0A}). The CRC for the SMS type is inclusively calcuated from the identifier to the terminating null byte.
 
+\subsection{TLE}
+
+TLE data packet starts with the \texttt{0x07} 1-byte payload identifier. Actual TLE data should follow as ASCII text strings (all 3 rows), separated by newline characters (\texttt{0x0A}). After the last character of the last row, a null character is added, followed by a 2-byte CRC.
