Electronics Offshore Navigation Chapter 8 1
Learning Objectives Understand benefits of AIS. Download and install VPP2. Install Capn, with charts. Use interactive pilot chart data. Plan & optimize offshore voyage with VPP2. Transfer WPTs from VPP2 to Capn. Use Capn to get in and out of harbor. Set alarms. 2
Computer Requirements Windows XP or Vista. Super VGA. Hard Disk Storage – at least 2 GB. DVD reader. High-speed internet connection. Printer. 3
Automatic Identification System (AIS) Electronic navigation tool Collision avoidance. Can identify vessel by MMSI, name, etc. Course, speed, type, destination, rate of turn, etc. AIS displays on Capn screen, if connected. Three version of AIS. Class A: required on commercial vessels. Receive only: available to recreational boaters. Class B – receive/transmit recently available to recreational boaters. 4
AIS Automatic Identification System Class B Transceiver 5
Advantages of AIS Greater range than radar on most boats. Not affected by rain or sea conditions. Can ‘see’ around corner or over bluff. Detects course changes sooner than radar. AIS targets do not merge. 6
