VueStar™ Manual- Rev B
Overview
VueStar™ is the only complete global aerial survey navigation system. VueStar™ delivers precision
navigation by combining NavCom’s leading edge, dual frequency GPS receiver with NavCom’s
StarFire™ Network, a Global Satellite Based Augmentation System (GSBAS). The VueStar™ system,
equipped with a single FAA certified tri-band antenna that receives both GPS and StarFire™ signals,
provides decimeter navigation in real-time without the need for local base stations.
The VueStar™ aerial survey package is the only system of its kind providing a reliable, cost-effective
solution for aerial surveyors. Maximizing the advantages of the global StarFire Network, the system
eliminates the range limitations of terrestrial communication links as well as the dependency on
postprocessing with ground based reference stations. Not only does VueStar™ provide surveyors with
the ability to return customer surveys in days rather than weeks, but it also frees ground based survey
crews to work on other projects.
The VueStar™ package comes complete with NavCom’s SF-2050M dual frequency receiver, all
necessary cabling, a combined GPS/StarFire™ FAA certified aircraft antenna, StarPac™ Utility
Software, a one-year global StarFire™ license, as well as detailed installation manuals and user guides.
An optional event latch interface can be purchased, which will allow greater connectivity between the
VueStar™ receiver and Photogrammetry cameras.
Purpose of This Document
The setup and operation of the VueStar™ System is described in the SF-2050 User Guide and the
StarPac™ User Guide. This VueStar™ Manual lists steps and information regarding the installation of
the Airborne Antenna as well as connectivity and set-up of the optional Event Latch Interface along
with all equipment described in this manual.

Aircraft Antenna
This section of the VueStar™ Manual is dedicated to the specifications for mounting the Airborne
Antenna to the fuselage of an airplane. Included within are measurements and spacing of hardware
based off of production designs, it is recommended to verify these measurements against the shipped
product before undertaking installation. All work should be performed by someone experienced with
aviation mechanics.
Included Materials
The Airborne Antenna includes the following items:
• 1 FAA Certified Airborne Antenna
• 4 Phillips Flat Head Mounting Screws
• 1 FCC Airworthiness Approval Certificate
Since aircraft and applications differ, nuts and washers have not been included. In order to
continue with installation, these items will need to be purchased/obtained independently and
in accordance to your unique situation.
Antenna Specifications and Mounting Guidelines
Optimum performance of the receiver is with a front end gain of 32—36 dB at the engine connector,
which the standard 12ft antenna cable shipped with the VueStar™ package delivers. However, other
cables can be used, as long as all the cables and connectors between the antenna and the RF front
end of the receiver experience no more than 3—7 dB of loss. Anything above or below 32—36 dB
could result in degraded receiver performance. It should, however, be understood that the receiver
has an overall operating dynamic gain range of 26—40dB, but operation on the extreme high and
low ends of this dynamic range are not recommended.
the entire sky. Any obstructions to this view will degrade position accuracy.
Mounting Requirements
Mounting the Airborne Antenna requires 5 holes; 4 for the mounting screws, and 1 for the TNC
connector which protrudes from beneath the antenna body. Reference the antenna spec sheet in
Figure 1 to determine the required size and relative spacing of the holes. Orientation of the antenna
is not as important as making sure that the antenna is flush against the body of the vehicle and tightly
held in place. (Figure 2)
Make sure the chosen location provides the antenna with a clear and unobstructed view of
o-ring that surrounds the connection. This will allow the o-ring to create an effective seal and
establish a secure connection point, free of air flow around the TNC connection.
When creating the hole for the TNC connector, be sure that it is smaller than the width of the
degree of variance compared to shipped antennas. It is strongly recommended to use the
antenna that will be mounted as a guide before creating any holes in the aircraft skin.
The measurements in Figure 1 are based off of production designs and may have a small

VueStar™ Manual- Rev B
The location of the antenna holes in the aircraft need to allow enough room on the inside of
the skin for the nuts to be threaded onto the mounting screws, as well as have enough space
for the antenna cable to connect to the TNC connector without putting pressure or tension on
the TNC connector, antenna cable, or connection. (Figure 3)
Once the desired location on the plane body is chosen and the measurements are correctly made,
consult the aircraft technical manual or a qualified aircraft technician about the proper tools and steps
needed in order to create the needed mounting and connector holes. Make sure to choose a location
that is not near crucial systems and that can withstand the strain of installation as well as the weight
of the antenna.

Event Latch Interface
This section is dedicated to installation and information about the optional Event Latch Interface. The
Event Latch Interface is designed to allow VueStar™ to have greater compatibility with more aerial
cameras and survey sensors. The Event Latch interface eliminates the requirement of 3-6V DC with
50 Ohm load input impedance, and since it is powered by the receiver, it only requires a simple
setup.
This section covers the specifications and installation of the Event Latch Interface, and includes
limited information about setting up a receiver to capture events. For further information on
receiver setup please consult the SF2050 Manual.
Event Latch Interface Specifications
The Event Latch Interface was designed to allow greater connectivity between the VueStar™ receiver
and Photogrammetry cameras. The Event Latch Interface (ELI) conditions and amplifies event pulse
output from cameras and other survey sensors so that the pulse can be successfully integrated with
the GPS receiver.
The ELI will support triggered rates of up to one pulse per second, provided that the pulse width is 10
microseconds or longer. The trigger source can be a simple off push button switch, or an electronic
switch such as an open/collect/ open drain device. Since the ELI is powered by the idle CAN bus on
the receiver the leakage current of the switch should be less then 1uA. If the trigger source is a real
electronic signal, then the pulse should have input voltage logic high 4—5.5V and logic low 0—0.4V
with a minimum 4mA sink current. The ELI will add a 12 microsecond delay to the time of an event.
The event latch is configured to trigger on the falling edge of the pulse. However, use of the
Event Latch Interface will condition the pulse appropriately, so the SF-2050M is able to accept
either rising or falling edge configurations (active high or active low).
Event Latch Interface Installation
Installation of the Event Latch Interface is very simple. Connect the LEMO connector to the EVT MKR/
CAN connector located at the back panel of the SF-2050M GPS Receiver. Input into the ELI is
through a female BNC connector, where the center pin is the signal and the outer shell is the ground.
