Usage regulations
Usage Regulations

  • Regulated by Federal Law

  • Government Users, or Data of Government Interest

  • Environmental Applications

  • Limited National Security

  • Non Competition with Private Sector


Statistics
Statistics

  • Approximately

    • 16,000 Active Platforms

    • 400 User Agencies

    • 100,00 messages per day


Transmitter characteristics
Transmitter Characteristics

  • Transmission Rates of 100, 300 or 1200 BPS

  • Most Have Multiple Sensors

  • Battery or Solar Powered, Some Electric

  • Remote Locations

  • Infrequent Maintenance Required

  • Most Newer Platforms have GPS for Timing Accuracy


Assignment characteristics
Assignment Characteristics

  • 200 Channels Available for Domestic Use

  • Most New Assignments Hourly

  • Most at 300 baud

    • No New 100 Baud Assignments Allowed

    • 1200 Baud Requires 2 Channels

      • Stringent Requirements for Message Length

  • Most Use Primary Self-Timed and Secondary Random Assignments


Random messages
Random Messages

  • Event Triggered

  • May Occur as Often as Every 2 Seconds

  • No Time Allocation Required

  • Specific Channels Set Aside for Random

  • Messages Transmitted Multiple Times to Avoid Collisions

  • Useful for Emergency Conditions When More Frequent Observations Required
