Peruvian satellite Chasqui-1 deployment

Peruvian satellite Chasqui-1 was carried to ISS on February 5th, 2014
by Progress M-22M. The battery power is completed in two days of August
14th and 15th, 2014. Chasqui-1 will be released by the astronaut in the 
spacewalk EVA-38 of ISS in the afternoon August 18th, 2014.
Please refer to the following web for more information.

Russian EVA-38 also features the deployment of a small satellite named
Chasqui 1 that was delivered to ISS in February by Progress M-22M.
The small 1-Unit CubeSat was developed at Universidad Nacional de
Ingenieria del Peru. The small satellite uses an aluminum framework
structure to provide stability to the satellite and offer mounting
surfaces for internal and external equipment.
The structural system of the satellite weighs 180 grams.

Chasqui 1 uses body-mounted solar cells for power generation with each
triple-junction cell measuring 8 by 4 centimeters allowing a total of 12
cells to be mounted on the external panels of the satellite. The solar
cells feed a Power Control Unit that employs Maximum Power Point Tracking
to generate the maximum power from the arrays based on current temperature
and illumination conditions. The Power Control Unit also distributes power
to the various satellite systems and controls the state of charge of
three Lithium-Ion batteries.

On average, the satellite generates 1 Watt of electrical power distributed
via a 3.3 and a 5-Volt power bus. All satellite functions are controlled
by an Onboard Computer module that measures 9.5 by 8.4 centimeters and
operates at a frequency of 4MHz.

Attitude Determination is accomplished by 12 sun sensors - one on each
external panel, one magnetometer unit and three angular velocity sensors.
A GPS receiver allows orbit determination with high precision. Attitude
actuation is ensured by a permanent magnet as a backup system to six
magnetic torquers. The satellite has a pointing accuracy of three degrees
in imaging mode and 20 degrees for communications sessions with ground
stations. Chasqui 1 uses the VHF and UHF bands for imagery downlink and
command uplink achieving data rates of up to 9600bps. 

The satellite carries two cameras - one operating in the visible wavelength
while the other acquires near-infrared imagery. The CMOS detectors of
the cameras provide images of 640 by 480 pixels. The two cameras will be
used to acquire images of Peru for agricultural monitoring and resource
management and the observation of deforestation and natural disasters.

During EVA-38, Chasqui 1 will be released into a retrograde direction by
the Cosmonauts to avoid re-contact with ISS on subsequent orbits and allow
the satellite to start out in an orbit slightly less than ISS that will
last for up to 10-12 months.

NCBR1 1k2 BPSK only2014年08月12日 23時07分

次のパスで、CWは無しで 1200bps BPSK のみを送信していることを確認しました。
信号強度が少し弱いです。事前にブラジル管制局から得ていた私信を紹介します。

Dear Mr. Wakita:

Thank you very much for helping us out tracking NanosatC-Br1 and 
reporting your findings through your site. To us, from the project team, 
this is paramount to take operation decisions.

I would like to inform also that due in great part to this support from 
amateur radios in Brazil and other parts of the world, we were able to 
return NanosatC-Br1 to its nominal mode since this morning here in Brazil.
