For a grid call, what is the minimum number of digits sent?

• A. Six digits
• B. Four digits
• C. Eight digits
• D. Ten digits

Answer: (A)

In a grid call, the target location is conveyed by its easting and northing within the chosen grid zone. You encode these coordinates with digits, using three digits for the easting and three digits for the northing. That six-digit combination pinpoints a 100-meter square within the grid, which is the smallest amount of digits that still gives a usable, precise location for firing data without wasting radio time. Using fewer digits would place the target in a larger 1-kilometer square (less precise), while more digits would increase precision (eight digits for about 10-meter precision, ten digits for about 1-meter), but six digits is the standard minimum for a grid call.
