Attachment A Planet Labs Inc. Earth Station Application January 2015 Page 1 of 4 Description of Request Planet Labs Inc. (“Planet Labs”) hereby requests authority to operate an earth station located at 5190 30th St. NE, Maddock, North Dakota. The proposed earth station will transmit at 2056.0 MHz and 450.0 MHz, and receive in the 8025 – 8400 MHz band and at 401.3 MHz. The earth station will be in communications with the authorized Planet Labs Constellation of Non-Geostationary Orbit (“NGSO”) Earth Exploration Satellite Service (“EESS”) satellites. 1 The frequencies in this application have already been authorized for transmission and reception to and from the authorized Planet Labs Constellation (known as the “Flock” series of satellite constellations). 2 The 8025-8400 MHz band, which is authorized for the Earth Exploration Satellite Service (“EESS”), is used as the primary space-to-Earth link. The 2025-2110 MHz band, which is authorized for EESS use subject to such conditions as may be applied on a case-by-case basis, is used as the primary Earth-to-space link.3 The 401-402 MHz band, which is authorized for Space Operations on a secondary basis for non- federal users, is used as a secondary TT&C space-to-Earth link.4 The 449.75-450.25 MHz band, which is authorized for space telecommand, subject to agreement obtained under No. 9.21, is used as a secondary TT&C Earth-to-space link.5 Planet Labs transmissions will not cause harmful interference to Federal and non- Federal stations operating in accordance with the Table of Frequency Allocations. Planet Labs also accepts any interference to it that is caused by those allocated services.                                                                                                                         1 See File No. SAT-LOA-20130626-00087 (approved 12/03/13), File No. SAT-MOD-20140321-00032 (approved 06/18/14), and File No. SAT-MOD-20140912-00100 (approved 10/23/14), Call Sign S2912. 2 Ibid.   3  See 47 C.F.R. § 2.106, footnote US347.   4 See 47 C.F.R. § 2.106; In the Matter of Orbital Imaging Corporation, DA 99-353, at ¶¶ 3,8 (1999). 5 See 47 C.F.R. § 2.106, footnote 5.286 and US87.

Attachment A Planet Labs Inc. Earth Station Application January 2015 Page 2 of 4 Additional Antenna Information   This Planet Labs earth station is comprised of two 5-meter parabolic “S/X-band” antennas controlled by X/Y rotators, and four “UHF” Yagi-Uda combination antennas. Each 5-meter parabolic antenna is housed inside a 7-meter radome. Each “UHF” Yagi- Uda combination antenna is unenclosed and is comprised of an “Uplink Yagi” and a “Downlink Yagi” mounted on a single cross-boom controlled by an Az/El rotator. Details are as follows: Table 1 “S/X-band” 5-meter Parabolic Antenna Characteristics Antenna Manufacturer Antenna Peak Gain 3dB Polarization & Model Diameter (dBi) Beamwidth (m) (deg) S/X-band CGC 5 50.4 @ X-band 0.25 @ X-band RHCP Parabolic 350SX(R) 39.0 @ S-band 1.0 @ S-band   Table 2 "UHF" Yagi-Uda Antenna Characteristics Antenna Manufacturer # of Antenna Peak 3dB Polarization & Model elements Length Gain Beamwidth (m) (dBi) (deg) Uplink M2 Inc. 17 2.7 16.5 30 RHCP Yagi 450CP34 Downlink M2 Inc. 15 2.7 16.5 30 RHCP Yagi 400CP30 Table 3 “S/X-band” 5-meter Parabolic Antenna Rotator Characteristics Manufacturer Type Radome Diameter (m) CGC X/Y 7.2   Table 4 "UHF" Yagi-Uda Antenna Rotator Characteristics Manufacturer Type Mast & Model Height (m) Yaesu Az/El 2.5 G5500
