WAAS RECEIVER
The Invicta 115 provides real time differential solutions using free corrections (WAAS) broadcast from
a satellite. WAAS corrections are available without a subscription free everywhere in the US, parts of
Canada, Mexico and Europe using a compatible system called EGNOS. These corrections are avail-
able 24 hours a day in all weather conditions.
GPS ANTENNA
The GPS antenna is a low profile patch antenna, which receives both GPS and WAAS signals. The
antenna is integrated in the receiver package.
UTILITY SOFTWARE
Utility software is not required to setup or use the receiver in most applications. However, a utility
program is available from Raven.
RECEIVER FIRMWARE UPDATES
Firmware is software, which resides inside the receiver. Raven continues to improve the performance
of its receiver products and sometimes makes special features available. When this happens, a new
version of firmware is created. A request can be made for this firmware from Raven. It will be neces-
sary to connect the receiver to a PC and run the included programming software to update the unit.
Check with a Raven dealer for a new version of firmware.
It should be noted that updates cover such things as bug fixes and performance enhancements.
Sometimes upgrades can also be programmed into the receiver using the utility software. Upgrades
also include things such as the 10 solutions per second option, which does have additional cost. The
good thing is that the user can install these upgrades and updates. It will necessary to get a code from
a Raven dealer or directly from Raven to install the upgrades but the process is simple.
SPECIAL FEATURES
The Invicta 115 has several special features that make it ideal for some applications. Raven is always
interested in adding special features to the receiver. If you have a good idea, please send us an email
at
or give us a call at 800-243-5435. We can’t guarantee that your idea will be
implemented, but we do want to consider it.
PPS OUT
The PPS output is normally used to provide a timing signal to another device. PPS stands for Pulse
Per Second and that’s what the signal does. Once each second the signal pulses to indicate the start
of a GPS second. The GPS second is a time reference, which can be used to synchronize systems.
If the application requires very accurate time then the PPS output may be required.
The PPS output can also be used as a RADAR or Speed log output as described in the following
sections.
