Page 4: Introduction
Accuracy depends on many factors including the correction method and the range from source. Primary concern with WAAS is that the Invicta 115 is designed to use this as the only source of DGPS corrections. Considering that today there is a limited number of WAAS reference stations, the accu- racy will vary from about 1 meter to 1.4 meters RMS depending on location. -

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. -

RADAR output. To use this feature, a special cable from RAVEN will be needed. It should be noted that the GPS can only determine speed when it is navigating. If a tree line blocks to many satellites or if for some other reason the Receiver is unable to navigate, then the RADAR output could become invalid. -

115 and repeat the previous step. At this point, the power is connected to the mounted receiver. The Invicta 115 will be looking for satel- lites, which may take a few minutes. Eventually, if the antenna has a clear view of the sky, the receiver will send data to the lightbar or other serial interface devise. -

15 minutes but is only required during the initial power up. Connect the serial cable provided between the Invicta 115 and the computer, apply power. Allow the receiver to operate while installing the software program on the computer. Turn off all unnecessary electrical equipment to minimize electrical noise interference. -

Satellite may be off the air. WAAS status information is available on the Internet at WWW.FAA….. Serial Coms – Using GPS MON software, check for proper communication settings baud rate, and COM Port number. Make sure the cable used, if not provided by raven, is wired correctly. See section titled “serial Interface”. -
Page 10: Receiver Specifications
CONFIGURATION “SERIAL INTERFACE” The Invicta 115 has two bi-directional RS232 serial interfaces available on a single external DB9 female connector. Each port is assigned a single letter in uppercase, ‘A’ or ‘B’ and each one provides the necessary interfacing between the Invicta 115 and your navigation equipment. -
Page 11: Global Positioning System (Gps)
GLOBAL POSITIONING SYSTEM (GPS) GPS is a satellite-based global navigation system created and operated by the United States Department of Defense (DOD). Originally intended solely to enhance military defense capabilities, GPS capabilities have expanded to provide highly accurate position and timing information for many civilian applications. An in-depth study of GPS is required to fully understand it, but not to see how it works or appreciate what it can do for you. -
Page 12: Differential Gps (Dgps) Waas
DIFFERENTIAL GPS (DGPS) WAAS DGPS works by placing a high-performance GPS receiver (reference station) at a known location. Since the receiver knows its exact location, it can determine the errors in the satellite signals. It does this by measuring the ranges to each satellite using the signals received and comparing these measured ranges to the actual ranges calculated from its known position. -
Page 13: Raven Proprietary Nmea Messages
NMEA MESSAGES The Invicta 115 receiver can be used to communicate with other electronic devices including Raven’s RGL 500 Swath Guidance Light bar. A communication protocol (set of rules) known as the NMEA 0183 standard has been established by the National Marine Electronics Association. The NMEA 0183 standard contains numerous message formats such as the ones described below which the Invicta 115 receiver uses to communicate with other devices. -

SAMPLE GGA MESSAGE STRUCTURE The following example of the GGA message shows the format typical of NMEA messages. -
Page 15: Limited Warranty
Bring the defective part, and proof of date of purchase, to your local dealer. If your dealer agrees with the warranty claim, he will send the part, and proof of purchase to his distributor or to Raven for final approval. WHAT WILL RAVEN INDUSTRIES DO? When our inspection proves the warranty claim, we will, at our option, repair or replace the defective part and pay for return freight. - Page 16 Manual Rev. A, Invicta 115, 12/02 #016-0159-912...
