The leading edge of the pulse is 4935 * coincident with the change of the GPS second. This is the same as 4936 * the change of the UTC second +/- ~1 microsecond. Some other clocks 4937 * specifically use a feature in the data message as a timing reference, but 4938 * the SVee Six Plus does not do this. In fact there is considerable jitter 4939 * on the timing of the messages, so this driver only supports the use 4940 * of the PPS pulse for accurate timing. Where it is determined that 4941 * the offset is way off, when first starting up ntpd for example, 4942 * the timing of the data stream is used until the offset becomes low enough 4943 * (|offset| < CLOCK_MAX), at which point the pps offset is used. 4944 * 4945 * It can use either option for receiving PPS information - the 'ppsclock' 4946 * stream pushed onto the serial data interface to timestamp the Carrier 4947 * Detect interrupts, where the 1PPS connects to the CD line. This only 4948 * works on SunOS 4.1.x currently. To select this, define PPSPPS in 4949 * Config.local. The other option is to use a pulse-stretcher/level-converter 4950 * to convert the PPS pulse into a RS232 start pulse & feed this into another 4951 * tty port. To use this option, define PPSCLK in Config.local. The pps input, 4952 * by whichever method, is handled in ntp_loopfilter.c 4953 * 4954 * The receiver uses a serial message protocol called Trimble Standard 4955 * Interface Protocol (it can support others but this driver only supports 4956 * TSIP). Messages in this protocol have the following form: 4957 * 4958 * <DLE><id> ... <data> ... <DLE><ETX> 4959 * 4960 * Any bytes within the <data> portion of value 10 hex (<DLE>) are doubled 4961 * on transmission and compressed back to one on reception. Otherwise 4962 * the values of data bytes can be anything. The serial interface is RS-422 4963 * asynchronous using 9600 baud, 8 data bits with odd party (**note** 9 bits 4964 * in total!), and 1 stop bit. The protocol supports byte, integer, single, 4965 * and double datatypes. Integers are two bytes, sent most significant first. 4966 * Singles are IEEE754 single precision floating point numbers (4 byte) sent 4967 * sign & exponent first. Doubles are IEEE754 double precision floating point 4968 * numbers (8 byte) sent sign & exponent first. 4969 * The receiver supports a large set of messages, only a small subset of 4970 * which are used here. From driver to receiver the following are used: 4971 * 4972 * ID Description 4973 * 4974 * 21 Request current time 4975 * 22 Mode Select 4976 * 2C Set/Request operating parameters 4977 * 2F Request UTC info 4978 * 35 Set/Request I/O options 4979 4980 * From receiver to driver the following are recognised: 4981 * 4982 * ID Description 4983 * 4984 * 41 GPS Time 4985 * 44 Satellite selection, PDOP, mode 4986 * 46 Receiver health 4987 * 4B Machine code/status 4988 * 4C Report operating parameters (debug only) 4989 * 4F UTC correction data (used to get leap second warnings) 4990 * 55 I/O options (debug only) 4991 * 4992 * All others are accepted but ignored. 4993 * 4994 */ 4995 4996 #define PI 3.1415926535898 /* lots of sig figs */ 4997 #define D2R PI/180.0 4998 4999 /*------------------------------------------------------------------- 5000 * sendcmd, sendbyte, sendetx, sendflt, sendint implement the command 5001 * interface to the receiver. 5002 * 5003 * CAVEAT: the sendflt, sendint routines are byte order dependend and 5004 * float implementation dependend - these must be converted to portable 5005 * versions ! 5006 * 5007 * CURRENT LIMITATION: float implementation.
