M-Cal - Dedicated Mooring Calibrator Program
Think of "M-Cal" as WorkBoat's little cousin making it even easier to calibrate the position of acoustic releases for any purpose: buoy anchors, sub-surface moorings, deep ocean instrument packages, hydrophone arrays, emergency location, etc. M-Cal is "checklist-driven" keeping even the most casual navigator on top of the problem of acoustically positioning their expensive bottom packages. M-Cal runs on Windows XP, 7, 8, and 10.
M-Cal supports acoustic transceivers including the popular EdgeTech 8011A and 8011M, the Benthos DS7000, UDB-9000 and UDB9400 series and their ATM880 and 9000 series ranging acoustic modems, and the LinkQuest acoustic modem. Mobilizing in just minutes, M-Cal inherits WorkBoat's I/O intelligence including the ability to feed the program UDP and TCP NMEA-0183 data over a LAN. With extensive HTML Help sub-system, navigators can even train themselves with a sophisticated simulator where they perform mock mooring calibrations and become familiar with the program.

The navigator has complete control of the generated solution including use of ranges, setting of maximum allowed error, 2-D vs. 3-D solution, etc. Calibrations may be halted and resumed later, loaded any time for display purposes, plotted on a graphical printer and more.
M-Cal provides the navigator with unprecedented control.
Like everything else in the real world, M-Cal's accuracy is determined by the quality of its inputs. Besides using an accurate speed of sound (set above), M-Cal provides complete control over geometrical details. And of course, the best GPS (i.e., differential), vessel heading input, the quality of your deckset's range measurement system and the sea-state determines the final outcome. Under ideal conditions, the final geodetic accuracy of M-Cal is roughly equivalent to the accuracy of your GPS system.
Example of M-Cal checklist: Precision dimensions and offsets are important for accuracy.
M-Cal: Affordable, easy to learn, easy to use and a very serious tool for anyone doing serious mooring work in the ocean.
