Sequence logic circuit 68 then directs counter 64 to count up or down toward zero, and gates system clock pulses to clock multiplexer circuit 70 which passes the clock pulses to counter 64 to count it to zero. Further, the preferred embodiment includes a display means for displaying the measured geodetic angle and also the time at which the measurement is made.

The sample counter 80 has a count of one pulse for the initial depression of the stellar sight button and an additional number of counts at one second intervals over which the average stellar sighting is taken. Linear Mode. Many marine stores carry navigation equipment such as compasses, charts, GPS devices etc.

Easy to order, discount on the item compared to what was seen on other websites, and delivery was FAST!!!! Divide by N circuit 76 may be a programmable divider circuit which puts out one output pulse for each N pulses received from clock multiplexer Lost Password?
