• Primary DCP collects and stores data from sensors
  and redundant RTU in various inputs (RS232,
  SDI12, analog, digital)
• Creates a pseudo-binary GOES message
• 96 bytes for a 5-second window
• 128 bytes for a 6 second window
• One redundant WL value ( previous 6 minute )
• Six 1 minute Tsunami values added to the end of
  the message
• Creates a PORTS Tag

• Sends setting to sensor
• Sets sensor time and date
• DCP polls the sensor
• Transmits the full data set via GOES
• Compression technique similar to that used for
  6-minute and hourly DCP data
• The pseudo Binary Data Transmission scheme
  reduces the size of the data file to fit the GOES
  1200 baud transmission slot.

Deployments of up to seven months have been
achieved because of the low power consumption of
both the profiler and radio. The entire package
weighs approximately 200 pounds and is easily
deployed using a small vessel and a block and
tackle. The current profiler is a 1-megahertz
(MHz) NortekUSA Aquadopp current profiler,
selected for compact size and low power
consumption. Data from each ATON system (fig.
1) are sent via radio to a data collection
platform (DCP) at a shore station. At the shore
station the data is transmitted via GOES to be
processed.
