POWERING ON THE 500S™
POWER CONSIDERATIONS
500S™ accepts an input voltage of 7-32 VDC. For best performance use a clean and
continuous power supply. When applying 12 VDC, 500S™ will draw approximately 3.2
W.
CONNECTING TO A POWER SOURCE
500S™ uses a single cable for power and data input/output.
Warning:
Do not apply a voltage higher than 32 VDC. This will damage the receiver
and void the warranty.
500S™ features reverse polarity protection to prevent excessive damage if the power
leads are accidentally reversed. With the application of power the 500S™
automatically proceeds through an internal startup sequence; however, it is ready to
communicate immediately.
500S™ OPERATION
Both GNSS and differential correction of 500S™ are preconfigured. The receiver will
work out of the box, and for most applications, little to no user setup is necessary.
When powered for the first time the 500S™ will perform a “cold start,” which involves
acquiring the available GNSS satellites in view and the SBAS differential service.
GNSS OPERATION
The GNSS internal receiver is always operating regardless of the mode of operation.
The following sections describe the general operation of the internal receiver.
AUTOMATIC TRACKING
The internal GNSS receiver of the 500S™ searches for GNSS satellites, acquires the
signals, and manages the navigation information required for positioning and
tracking.
RECEIVER PERFORMANCE
The 500S™ works by finding four or more GNSS satellites in the visible sky and uses
information from the satellites to compute a position within 2.5 m (98.5”). Since there
is some error in the GNSS data calculations, the 500S™ also tracks a differential
