paper describing the development
and
testing of phasorBIRD - Ascension's
next generation helmet tracker.
Helmet-Mounted Sights
 Ascension’s second-generation
DC magnetic and next-generation
optical head trackers optimize
the effectiveness of helmet-mounted
display systems in combat
vehicles – air and ground.
By accurately measuring a
pilot’s line-of-sight (LOS)
angles, they permit precision
guidance of weapons, enable
intra-cockpit cueing, and
maximize situational awareness.
In short, pilots can aim weapons,
acquire mission-critical information
and receive self-protection
prompts simply by looking
at a target through their
visor.
Magnetic Helmet-Mounted
Sights
 Flight
worthy models of Ascension’s
DC magnetic tracker are available
from Ascension’s licensee
for DC technology, BAE Systems
Avionics, Rochester, UK. BAE
is the largest avionics company
in Europe and the UK’s foremost
supplier of electronic systems
for military and civilian
air platforms.
In the last decade, BAE has
developed a family of helmet-mounted
displays for fast jet and
rotary aircraft applications.
DC magnetic tracking, which
greatly simplifies installation
mapping compared to earlier
AC magnetic trackers, is used
for target acquisition and
cueing in head-mounted displays
system. Current programs include
the German UH-Tiger helicopter
and the AH-1Z helicopter upgrade
for the US Marine Corps.

Next generation Optical
Tracking
In response to DOD requirements
for advanced tracker technology
integrated with new helmet-display
concepts, Ascension has developed
phasorBIRD™
-- a breakthrough innovation
in optical head tracking.
phasorBIRD is a six degrees-of-freedom
tracker designed to meet next
generation accuracy and measurement
rates ( 0.1°/+300Hz )
while being compatible with
night-vision systems. Upon
program completion, it will
also be immune to ambient
light as well as cockpit and
helmet scatterers of magnetic/electric
field energy.
phasorBIRD technology overcomes
performance, mounting, and
human-factors limitations
inherent in lens-based cameras
employing bulky, obstructive
emitters. It also eliminates
the requirement for elaborate
alignment and mapping hardware
with its accompanying high
logistical costs.
A Phase I phasorBIRD model
is presently operational.
Two additional developmental
phases are anticipated prior
to product release.
Prototype development, suitable
for airborne testing, is presently
in progress under the direction
of the Air Force Research
Lab (AFRL) at Wright-Patterson
AFB, OH.
