John – one correction, as reflected below (for the gateway downlink, the power density is -45.6 dBW/Hz, not -23
dBW/Hz). Otherwise the emission designators and other information you listed was correct. Sorry to be slow in getting
back to you, but we had to dig the 1993 application out of the files to make sure we had the information right.

Mr. Goodman,

Any response from Orbcomm verifying the information below?

Please verify that the transmitter on the satellite serving as the downlink to the
Gateway earth station has the emission 44K0G1D at 11.2 watts peak ERP and a power density
of -45.6 dBW/Hz-23 dBW/Hz, and the satellite serving as the downlink to the Subscriber
earth station has the emission 10K4G1D at 20 watts peak ERP and a power density of -23
dBW/Hz. Please make corrections to the aforesaid if necessary.

You may already be doing so with the Orbcomm engineers, but if not, please verify
that the transmitter on the satellite serving as the downlink to the Gateway earth
station has the emission 44K0G1D at 11.2 watts peak ERP and a power density of -23
dBW/Hz, and the satellite serving as the downlink to the Subscriber earth station
has the emission 10K4G1D at 20 watts peak ERP and a power density of -23 dBW/Hz.
Please make corrections to the aforesaid if necessary.

Mr. Goodman,

I also need to know the name being given to the satellite that will be
launched.

Mr. Goodman,

Pursuant to our telephone conversation today, please verify that the
transmitter on the satellite serving as the downlink to the Gateway earth
station has the emission 44K0G1D at 11.2 watts peak ERP and a power density of
-23 dBW/Hz, and the satellite serving as the downlink to the Subscriber earth
station has the emission 10K4G1D at 20 watts peak ERP and a power density of -
23 dBW/Hz. Please make corrections to the aforesaid if necessary.

John:

The Subscriber Transmitter on board the satellite is powered at 20 W
across a 4 kHz bandwidth.
The power density is therefore 20/4,000=.005W/Hz. Converting to
dBW/Hz, 10log10(.005)= -23dBW/Hz.

Please let me know if you need anything else.

John – following are the responses to your information request.
Please let me know if there is anything else you need. Thank
you in advance for your prompt attention to this matter.

Steve Goodman
Counsel for ORBCOMM

1. Are you requesting expedite processing? If so, please
justify the need for expedited processing:

Yes, ORBCOMM is requesting expedited processing in order to
allow the launch of the satellite to occur as planned in the
Third Quarter of this year. The satellite is a concept
demonstration program for the U.S. Coast Guard (Contract #
HSCG23-04-C-ADA001) as part of its mission to monitor ships at
sea, a critical element of the Coast Guard’s homeland security
role. Thus, expedited processing of this experimental
application will well serve the public interest.

2. Please report the following satellite information
specifically pertaining to 0108-EX-PL-2006:

Geostationary or Non-Geostationary: Non-Geostationary

Earth Coverage or Narrow Beam: Earth Coverage

Antenna Polarization: Right Hand Circular (RHCP)

Equatorial Inclination Angle: 83 degrees

Message Page 4 of 6

Apogee in Kilometers: 950 kilometers

Perigee in Kilometers: 950 kilometers

Period in Hours: 1.73 hr (104 min)

Number of satellites: We are seeking experimental authority for
just one satellite.

Downlink Peak Effective Radiated Power: 11.20 W

Downlink Emission Designator: 44K0G1D

3. Please report the following earth station information
specifically pertaining to 0108-EX-PL-2006:

ORBCOMM will use all four of its licensed U.S. Gateway Earth
Stations to communicate with the satellite.

St Johns Arizona North 34 27 23 West 109
33 16

Arcade New York North 42 31 29 West 78
22 57

East Wenatchee Washington North 47 33 12 West 120
10 25

Ocilla Georgia North 31 30 3 West 83
11 0

Uplink Peak Effective Radiated Power: 6.100000 kW

Uplink Emission Designator: 50K0G7D

4. Please verify that the 0108-EX-PL-2006 downlink and uplink
bands both
137-138 MHz. If they are different, please report the
following:

Downlink (Satellite) Band: 137-138 MHz

Uplink (Earth Station) Band: The satellite will be monitoring
AIS transmissions in the 161-163 MHz band, and the Gateway
Earth Station uplinks will be in the 148-150.05 MHz band.

6/6/2006

However, ORBCOMM is not seeking experimental authority for the
uplink transmissions, because those are already licensed.

Subject: Clarification

John:

In order to clarify the material I previously sent you with regard to the
ORBCOMM gateway earth stations (“GESs”), following is the requested
information:

The GESs track the satellites as they move across the sky. Thus, the Azimuth is
0 to 360 degrees, and the Elevation Angle is 0 to 180 degrees.

The Beamwidth is 23 degrees.

The Gain is 17 dB at the center frequency along the axial boresight.

Finally, Polarization is left and right hand circular.

Please let me know if you need anything else. Thank you.
