Attention! the program is in it's beta stage. it is neither tested nor documented thoroughly enough
Attention! bluetooth connection process is slow. experiments show that connections and disconnections can get 30 seconds (this seem to be a fundamental property of the system). after all connections has been setup, they work well. tested configuration: Tungsten T and two bluetooth receivers, one setup to NMEA and the other to SiRF.

Though this is a free (in rms sense) program, PalmOS is not, and never will be. I don't know whether they want to free the system or not, however they can't do this on their own, because PalmOS was based on a system that belonged to another firm. I distinctly realize that, therefore I write nauta for fun and self-education.
System requirements: PalmOS 3.5 and higher.
The archive contains the nauta 4?15l (first patch level) (October17) which includes the following files:
|nauta.prc||nauta for Palm (the main application)|
|tiedb.pdb||table of transitions on keypresses|
|coreform.prc||programme core settings|
|gpsform.prc||satellites and measurements status|
|logform.prc||tracks with comments are logged to a file|
|frmn.pdb||instructions for menuform.prc|
|navform.prc||position and velocity|
|rmlog.prc||application to quickly delete nauta's logs|
|rtcmparser.prc||simple parser for DGPS corrections|
|skyform.prc||the same data as in gpsform.prc in graphs.|
|trackform.prc||the ways passed with receivers|
|statform.prc||current and medium position, root-mean-squares.|
|syncform.prc||Palm time and UTC difference; clock correction|
$ make utilsthen the utilities should appear in bin/utils/.
The main application. he has no forms besides auxiliary. he controls all the rest. he reads in tiedb.pdb his table of transitions between forms on keypresses. he writes his events in /var/lib/nauta/log. they can be read after conversion with db2txt program. in released versions, those logs are not so verbose, but you will have to delete them from time to time. I use FileZ and my rmlog.
The entering from sources data are passed to parsers (..parser.prc). the parser converts these data in messages, then the messages are fetched to the current form (..form.prc). now this latter form displays the data in accordance to her will. certain parsers can be feeders. such a parser produces from it's source differential corrections and sends them to sources.
A pipe includes a source, a feeder, a parser and a database whither the data are written. the data can be displayed or not, written or not. all this can be customized at preferences form (prefsform.prc). All pipes, no pipes and single pipe can also be quickly selected. this is performed with a popup list in the upper left corner. multiple simultaneous channels are supported. now trackform.prc is the only one that distinguishes messages from different sources. multiple channels can be useful if data from several sources need to be logged at the same time. of course, the hardware must admit this.
This converts all the data to text messages. they can be seen at the Scroll form.
Nauta core: settings and state.
Measurements state, number and list of satellites in use, and in which directions they are seen, and dilusions of precision.
The only difference from asciiparser.prc is that this transforms the data to hexadecimal form.
Current positions with user comments are written into a database. in the upper part the current measurement and free memory are shown. then the write interval in seconds is shown and can be modified. after that there are the comments list. the comments can be selected, deleted, corrected and added. you can select them from the list in the usual for PalmOS way or with >Up< and >Down< keys, as well as via graffitying the first letter of the comment. in the lower part the database in which the measurements and comments are written is defined.
If an external memory card was used, copy the logged file to a less portable machine. in the file you can see lines like these:
@Palm date: 23/6/1976 63230000 200580001 134880002 10200 2 @GPS date: 23/6/1976 63240000 200580003 134880004 10200 3 #Pooh Corner 63257000 200580005 134880006 10200 1 63270000 200580007 134880008 10200 2 #oak (or birk?) 63280000 200580009 134880010 10200 2 63290000 200580001 134880003 10200 2 #well 63310000 200580002 134880004 10200 2
The lines in "#" are user's comments; "@Palm date:" goes from PalmOS; "@GPS date:" is the date from the receiver. the other lines are measurements: the first position is UTC in milliseconds; the second — latitude in milliseconds; the third — longitude in milliseconds; the fourth — altitude in centimeters; the last sign is the measurement quality (0 - no measurement; 2 - two-dimensional; 3 - three-dimensional).
If the log is written in the Palm internal memory, it can be translated to the same form with db2txt itility.
In this form the other forms are listed and hither can be reached. the buttons positions are written in frmn.pdb. if this database is absent, a new one is created, in which all present forms are collected. we can go to this form with >Menu< button.
Time, curent position and speed with large font.
NMEA parser. It can read about messages structure from it's dababase (dbnmea.pdb), but even without the database it knows enough. this is why dbnmea.pdb is not included in the distribution.
The program preferences.
Parser for differential corrections management. it sends all entering data with no transform to defined sources.
Here the entering data run.
SiRF (Trimble binary protocol) parser.
It writes time, position, dilusions of precision, draws signal-to-noise ratio and satellites in the sky.
Time, current and mean position. RMS is estimated. of course, it is not the error magnitude, only degree of difference between measurements at the observation timespan.
Palm time, UTC, the difference. Palm clock can be corrected.
Palm features: free memory, time, serial ports, the device serial number.
The ways passed are drawn. different sources are distinguished. the receiver current position is designated with the pipe number. the scale of the drawing is written at the left upper corner.
TSIP (Trimble binary protocol) parser.
Nauta creates files in the Palm memory. if you transfer them in any way to another computer you can convert it to a file containing data as they are written. all you need is to run db2txt like this:
$ db2txt nautadb.pdb nautadb.dat
The result will be written in nautadb.dat.
Use them to change buttons in menuform.prc. I won't describe here the format, but you can read an example in the sources.
The same for the transitions table tiedb.pdb.
See the program tips and NMEA 0183 documentation. TSIP description is available at Trimble home page.
