iNav Pro AtoN Network and VDL Analysis Software

Ideal for: monitoring AtoN positioning

In the early days of AIS little was known about how the AIS VHF-FM Data Link (VDL) and AIS radios were actually performing.  A few of the more ambitious and technically savvy AIS folks designed some rudimentary analysis tools for their own specific purposes but such activity was very limited and not suitable for a more general use.

A few AIS gurus involved in AIS from its inception thought there was a better way.  iNAVPro AIS Analysis software is the result.  Through a series of software development iterations, each building on the real-world experience of experts using the software, iNAVPro is now a very robust tool to aid AIS authorities in managing their AIS network. 

iNAVPro can integrate with various hardware and software to offer the user an outstanding platform for AIS analysis:

• Compatible with all IEC Base Station Receivers
• Decodes VSI sentences
• Supports all Shine Micro SM1610-4 $PSHI sentences
• Integrates with MS SQL Server for Data Base support

iNAVPro Functions and Options available to the user include the ability to:

• Access all the functionality of the standard iNAV software
• View VDL loading by any combination of Target Classes and Message Types
• View cumulative VDL slot usage by any combination of Target Classes
• View interactive Slot Map by any combination of Target Classes
• View Slot Reservation v. actual Slot Usage statistics
• View Frame Statistics by Epoch and High Message count Targets per IALA A-124/18
• Determine true VDL Loading by accounting for “occupied” slots due to slot collisions, undecoded messages and detected energy in the slot
• Detect AIS radios transmitting outside ITU specifications (jitter, frequency offset and deviation)1
• Identify and autonomously notify targets that transmit incorrect Dynamic Data
• Identify and autonomously notify targets that transmit incorrect or incomplete Static Data
• Identify Class A and B targets that do not comply with Individual and Group Assigned Mode commands
• Draw Area Cover Maps by signal strength and vessel tracks for each Base Station or other AIS Receiver
• Produce Line Passage Statistics and Traffic Density Plots
• Monitor Base Stations and Atons for correct FATDMA Slot Usage
• Monitor Base Stations and Atons for signal strength over time
