The work is aimed on the improvement and testing of the subsystems of the university nanosatellite (NS) of Cubesat format through the development, modeling and research of service subsystems to ensure the payload - an optical-electronic scanner with the ability to image the Earth's surface in the visible light range with the resolution of 15m to 30m when operating in orbit with an altitude from 400 km to 700 km, by the efforts of students, master's students, post-graduate students and research staff of Igor Sikorsky Kyiv polytechnic institute.

There are done improved development and modeling, manufacturing and research of subsystems - power supply, navigation and orientation with a flywheel - electromagnetic executing mechanism and sensors for determining the coordinates of the Sun, high-speed radio communication and telemetry, an optoelectronic scanner, control and data processing - a flight model of a nanosatellite (NS) PolyITAN-3 -PUT 3U CubeSat format for remote sensing of the Earth. Including were:
1. Manufactured and tested:
- design of the case and solar panels for power supply (EPP) NS,

The work is aimed at creating a universal power supply subsystem for nanosatellites, which will be able to provide high-quality power to space devices - precision GPS \ GLONASS receiver and optoelectronic scanner (OEC) as a payload of GraviSat and PolyITAN-3.

The work is devoted to the creation of a nanosatellite (CdS) format Cubesat, 3U by developing, modeling and researching efficient service subsystems to provide a payload - an opto- electronic scanner with a capability of shooting in the range of up to 30 m when it operates in orbit at altitudes up to 700 km.
The above works are carried out by the students of the undergraduate, postgraduate students and research staff of the following faculties: TEF, PTF, FEL, FAA, PBF and MMI, as well as attract specialists of PJSC "Pivdenne" (Dnipropetrovsk) as consultants.

Object of research is the educational nanosatellite (further NS) a format 2U CubeSat.
Objects of research are a subsystem of navigation for NS on an earth orbit with receiver GPS/GLONASS, a subsystem of orientation of NS, a subsystem of communication of NS to ground station with a format of data interchange AX.25 and BPSK modulation.
The operation purpose is development of subsystems of navigation, orientation and communication of NS by methods of physical modeling and an experimental research of the main parameters of subsystems.

For the first time in Ukraine team of students and teachers has developed experimental flight model of nanosatellite and structural - technological methods for ensuring of thermal conditions of all nanosatellite subsystems. Namely, onboard the data processing subsystem with the help of onboard computer and software applications, three axes attitude determination and control subsystem with sun sensors, radio frequency link telecommunication subsystem, telemetry tracking and control subsystem, electric power supply subsystem.

Bases of creation of midget space vehicles  as space microlaboratories are worked out. Theoretical and experimental researches are conducted on creation of the systems of microsatellites, basic scheme-technical decisions are worked out, software is developed. The ground center of communication with microsatellites in the amateur range of frequencies for realization of space experiments is created
