Information on decoding the Sony IPS Data Format for Position Output:

The IPS-2010 transmits position data every one second.
This data format is similar to the IPS-3000, which includes 108 ASCII characters, "Carriage Return" and "Line feed".
The sample data is as follows with referencing letters underneath each field.

--------------------------------------------
Commands to your IPS-2010
--------------------------------------------

You need to put @ character on the beginning of command.

PT: Enter Approximate position of where you are
  At system reset or moving over 2000km with out receiving signal, or after a memory clear
  Entering this command makes faster positioning than Automatic .
  Example:@PTS35E139<CR><LF>
      (N or S,Lat(Degree),E or W,Lon(Degree)

TM: Enter Approximate UTC time & date
  Example:@TM199703042120000<CR><LF>
        (UTC date and day of week and time)

SK: Enter a Local Map Datum
  Example:@SKA<CR><LF>
        (A=WGS-84 U=AGD84... See earlier table)

DMD:Set Lat and Lon as DMD
Example:@DMD<CR><LF>
Lat and Lon indicate as deg,min,1/1000min

DMS:Set Lat and Lon as DMS
Example:@DMS<CR><LF>
Lat and Lon indicate as deg,min,1/10sec

SR:Software Reset
Example:@SR<CR><LF>
Erase settings of CH command

CD:System Reset
Example:@CD<CR><LF>
Reset all in memory and set as default
Exact Place:Tokyo
Exact Date :random
DATUM :WGS-84
Indicate way of Lat and Lon:DMS

CH:Set SV# of satellites to receive(Fix satellites)
Example:@CH3,5,9,13,21,18<CR><LF>
Available number is 1 to 32
Way to clear this setting is
SR or CD command and CH command with out parameter.

SV:Calculate number of visible satellites of day
Example:@SV<CR><LF>
DFEEEFD...........................means
|||||||01:30 D(3)
|||||| F(5)
|||||01:00 E(4)
|||| ov 30 deg. E(4)
|||00:30 ov 30 deg. E(4)
||00:00 over 10 deg. from Holizon is F(5)
|00:00 over 30 deg. from Holizon is D(3)

A=0...K=10

LS:Calculate visible satellites of day (each 30 min)
Example:@LS<CR><LF>
05 DF
||over 10 deg. from Horizon is F(5)
|over 30 deg. from Horizon is D(3)
05 is 02:30 UTC
