Back 40 Precision Inc.

back 40 precision designs and manufactures their own line of precision equipment including the rtkonnect and industry exclusive ntrip client device that utilizes both wifi & bluetooth via serial cable for ease of secure in cab connectivity. in most cases this replaces the use of a modem and data plan. no need for an expensive static ip. back 40’s caster program uses a proprietary algorithm to calculate multi frequency code and phase measurements to create an accurate model of the current ionospheric layer. the majority of the systems in ag. only calculate to the first order. back 40 stands out as being the only company that has integrated 2nd and 3rd order error terms. this innovative breakthrough significantly reduces range error during high solar activity. during average solar activity 2nd and 3rd order terms are negligible and account for less than a few millimeters of error. however, during solar flares the second and third order terms, when left unaccounted for, can add up to 25 c
