      Subject: Request for Special Temporary Authority to operate up to 5
                  Aeronautical Mobile Satellite Service Terminals

         Dear Mr. Tycz,

        Pursuant to Section 25.119 of the Commission‘s Rules, CAL Corporation ("CAL")
hereby requests Special Temporary Authority ("STA") to operate up to 5, two—channel
aeronautical terminals satellite terminals pursuant to the attached technical exhibit.
The terminals will operate on space segment provided by AMSC Subsidiary
Corporation. CAL requests that the STA become effective March 10, 1997 and remain in
effect until September 7. 1997 or until a grant of CAL‘s type acceptance application ,
whichever is earlier. Grant of this request will serve the public interest in the
continued development of MSS in the United States.

(1992) CAL also has notxfied the FAAof 1ts intention to make application for type
acceptance, including all the required technical data, and will provide the FAA a copy of
the final type acceptance application submitted to the FCC.

The purpose of the authority requested herein is to allow CAL to conduct end—to—end
tests of the two—channel terminals, using the AMSC communications ground segment,
control systems and satellite. The tests also permit CAL to comply with FAA type
acceptance requirements for specific aircraft models. CAL seeks to conduct tests
covering system stability and quality, as well as feature and service functionality to
provide mobile satellite services. All participants in these tests will be notified that the
terminals have not yet been type accepted and are returnable to CAL if type acceptance
is denied. Participants will pay AMSC for appli           —
trials are to be conducted in the US and in Canada.
                                                                 Granted

(Chief of Division)


These tests represent an important step in the continued development of aeronautical
mobile services. Currently, general aviation and corporate aircraft have been unable to
receive two—channel, high—quality voice, data and fax service at reasonable rates. The
authority requested herein will allow CAL to ensure that the terminals are technically
sound‘ and meet all operational requirements prior to the full commencement of
services to the public. Therefore, CAL respectfully requests temporary authority to
operate up to 5 two—channel aeronautical satellite terminals, consistent with the
parameters set forth herein. CAL requests that this STA be granted effective March 10,
and last for six months, or until grant of the underlying type acceptance application,
whichever is earlier.

CAL certifies that no party to this application is subject to a denial of Federal benefits
pursuant to Section 5301 of the Anti—Drug Abuse Act of 1988, 21 USC § 835(a).


                                                       Respectfully submitted,

                                          (STA)
DESCRIPTION OF EQUIPMENT:
Purpose of Equipment

       The equipment is intended to provide dual channel voice, FAX and data services
in the Aeronautical Mobile Satellite Service. Specifically, it supports the following data
rates and services:

       o     4800 bps digitized voice using the DVSI IMBE vocoder.
       e     2400 bps Group 3 FAX.
       e     4800, 2400 and 1200 bps circuit switched data.

      These services are made available to the maximum extent practicable during all
phases of aircraft operation, both on the ground and in the air.


Equipment Configuration

       The equipment will be provided in one of two possible configurations at the
customers discretion, single channel or dual channel. The single channel installation
has been the subject of a previous Type Acceptance application and received
certification under the FCC ID: K6KQC100. The Grant of Equipment Authorization is
filed with the FCC under File number 31010/EQU 17.9, dated March 6, 1996. The dual
channel configuration is identical to the single channel except that two transceiver
subsystems are coupled to the same antenna through a 34B hybrid coupler. The dual
channel configuration is shown in figure 1. The major active elements are as follows:

      1. The Antenna Unit

      2. The Transceiver Subsystem

      3. The High Power Amplifier (HPA)

      4. The Two Channel Coupler Unit

      5. The Handset(s)

   A brief description of each element follows.
Antenna Unit

       The Antenna Unit is designed for fuselage top mounting. It includes a
mechanically steered radiating element and motor drive, and is covered by an
aerodynamically contoured radome. The Antenna Unit and its radome also house: the
diplexer and LNA combination, a compass to provide steering information, and an
active GPS antenna element.


Transceiver Subsystem

       Each Transceiver Subsystem (TS) includes the Transceiver Unit (TU), the High
Power Amplifier (HPA), the beam steering unit (BSU), a GPS receiver and a power
converter to suit the aircraft supply. The TU performs all the functions defined for this
unit in its land mobile configuration plus providing Doppler correction through the
use of software specially developed for aeronautical applications. The GPS receiver
provides position and velocity information both for Doppler correction and for use by
the BSU in steering the antenna. The two Transceiver Subsystems in the two—channel
configuration are functionally identical to that used in the single channel configuration
and are completely interchangeable. The special configuration required for them to
operate as designated units #1 and #2 in this two—channel configuration results from
signaling from the micro—processor in the two—channel combiner to the unit installed
in the #2 position.
High Power Amplifier

       The HPA is required to amplify the transmit signal given out by the TU to the
level required to meet the specified EIRP requirements. It is co—located with the
Transceiver.

Two Channel Coupler Unit

       The Two Channel Combiner Unit provides the RF interface between the two
transceivers and the single Antenna.   It also provides information, to the transceiver in
the # 2 position, on the status of the transceiver in the # 1 position. This allows the
#2 Transceiver to disable itself and bypass the hybrid combiner in the #1 transmitted
path, when traveling in areas of the coverage where only single channel operation is
available.
Number of Handsets

       Each of the two transceiver units is to be supplied with a single handset.
Provision will also be made for the installation of multiple handsets, all connected to
both TS‘s so that any one of them can be used to communicate through either channel.
Handsets

       In addition to their primary communication function, one of the handsets will
have keys and a display, and is to be used as the control panel for the equipment.

Installation Issues

       The equipment is designed for simple, straightforward installation to minimize
the cost of this activity. To this end, the following guidelines are followed:

o      Minimize the size and weight of the antenna.

o      Minimize the size and weight of the interior equipment.

e      Installation will be possible without removal of the antenna from the radome.

o      The GPS antenna will be incorporated within the main antenna assembly to
       avoid having to install a separate unit.
Range of Aircraft Sizes

       Provision is made for installing the antenna on fuselages in any one of five size
ranges. These ranges encompass most of the commonly used private commuter
aircraft in service.
Cabling Details

       The system is designed to maximize the length, and minimize the diameter, of
the cabling interconnecting the various subsystems.
Power Distribution

       Power is processed in the Transceiver Subsystem and then distributed to the
other subsystems to avoid the need for more than one supply from the aircraft.
Connector
       Circular avionics style bayonet connectors are used wherever possible.
Mounting
       The handset(s) will normally be cradle mounted on a cabin wall or other vertical
surface.



MANUEACTURERS IDENTIFICATION:

       The product will be identified as a: CALQUEST*Y Satellite Phone, model CQ200.




February 12, 1997                                                         Page 4


ANTENNA CHARACTERISTICS:

       The gain of the antenna is measured at the input to the antenna element (ie.,
not at the input to the Antenna Unit). The beam peak gain varies with the antenna
pointing orientation, but lies within the following ranges:


                                         Receive band           8.3 dBi to 12.3 dBi
                                        Transmit band           9.4 dBi to 12.3 dBi




       The relative transmit antenna gain pattern envelope (i.e., spatial discrimination)
for the AES antenna is strongly dependent on the mechanical pointing direction of the
antenna relative to the fixed ground plane. Although the requirements for off—axis
antenna discrimination nominally apply only to the "horizontal" (e.g., equatorial)
plane of the antenna gain characteristic, the complex geometry of a mechanically
steered antenna mounted on a maneuvering aircraft significantly broadens this
requirement when the gain is referenced to the antenna‘s horizontal and vertical. In
order to satisfy all potential geometrys of satellite pointing direction, aircraft orientation
and consequent antenna orientation for satellite pointing, the antenna gain envelope
contours were analyzed to determine the highest off axis antenna gain at any angle
relative to its horizontal / vertical reference planes. These worst case off—axis spatial
discrimination gain results were then compared with the maximum allowable off—axis
relative gain illustrated in Figure 3 below:

                                                                              75° away from the nominal

The following plot, Figure 4, illustrates the results of the analysis measured with an
antenna elevation angle of 45° where the off axis gain, when measured at the various
azimuth pointing angles shown as parameters, was the maximum recorded. In the
worst case this indicates there is still a 5° margin in the off—axis discrimination
performance.

RATED OUTPUT POWER:

       During periods when a single carrier is activated, and within the constraints of
the Signal Timing Limits, the EIRP lies within the range +12.0 dBW to +18.3 dBW.

During periods when both carriers are activated, and within the constraints of the
Signal Timing Limits, the EIRP lies within the range +9.9 dBW to +15 dBW.

The maximum level is not exceeded even when the antenna peak transmit gain is not
in the direction of the desired satellite.

      It is recognized, and so noted in the installation / operators handbook, that this
system may not be operated at the same time, and on the same aircraft, as the
GLONASS navigation system.



CRITERIA FOR PRIORITY AND PREEMPTIVE ACCESS:

      The CALQUEST!Y Aircraft Earth Station incorporates a transceiver which is
similar to the Westinghouse equipment used in the AMSC Mobile Telephone
System(MTS), for which AMSC has previously received operational authority from the
ECC and which has been found, by the FCC, to meet its requirements for Priority and
Real Time Preemptive Access.
