1. Each line of data can be identified amp summarized as follows L Doppler Fix This will be an Argos calculated Doppler fix based upon the messages received from the PTT by an Argos satellite This line of data will contain the Lat Long date amp time of fix GMT location quality accuracy amp satellite name GPS Fix This line contains a GPS fix and corresponding data transmitted by the PTT This line of data will contain the Lat Long date amp time of fix GMT accuracy GPS acquisition time in seconds etc Sensor Data This represents a message received that is transmitted by the PTT that contains sensor data such as voltage temperature activity transmission counter etc Typically on a GPS PTT this sensor data message is sent in one out of every 5 transmissions with all other transmissions messages containing GPS location data On Doppler only PTT s this sensor data is sent in every transmission with each message containing certain pieces of sensor info amp cycled through in a round robin fashion in order to send out all pertinent sensor data NOTE The example images amp data included within this documentation is for a GPS PTT The Doppler only PTT data will look very similar with the exception of GPS fixes not being present When looking at GPS PTT data as shown above it is important to understand that there are likely many more messages received from the PTT than what is reflected in DSDCODE The reason for this i2. 02 AA 1A B2 03

5. DSDCODE Software User Manual Introduction DSDCODE is a simple program that allows the user to process an Argos DS data file and display the location and sensor data in an easy to read format The decoding process will also create a generic database file in dbf format that can be opened using any software application that supports this format such as Microsoft Excel The DS file that is to be processed can contain multiple Argos ID s and the result will be a single dbf file that will be created for each Argos ID If subsequent DS files are processed from the same folder location on the user s PC any additional data for an Argos ID that was previously processed will be appended to the existing dbf file and allow the user to maintain a cumulative set of data for each Argos ID in one file In addition the Argos ID data displayed within the DSDCODE program will also be cumulative While DSDCODE is not required to view Doppler location data contained in DS data files it is required in order to decode the GPS fixes as well as the sensor data transmitted from the PTT s Sensor data if equipped and available include GPC fix info battery voltage temperature activity etc Installation The installation of the DSDCODE software is very easy in that the program file executable merely needs to be copied to your hard drive and run from that location To launch the application simply double click on the file dsdcode4 exe Included wit
