According to the National Space Program of Ukraine on 1998-2002 the experimental space system WARNING has to be designed and launched in 2001. The main goal of the WARNING mission is investigation of lithosphere-atmosphere-ionosphere-magnetosphere interaction and searching for the probable earthquake precursors. The present meeting has been called in accordance with the decision of previous meeting in Kyiv (October 28-29, 1997) in order to agree payload composition and space configuration of three WARNING satellites. Meeting participants from Bulgaria, Hungary, Russia, USA, Czech republic and Ukraine presented their proposals. The decisions of meeting are the next.

1. To compose experimental space complex WARNING from three satellites:

2. The space vehicles are to be designed, created, launched and operated by Ukrainian organizations and firms. Composition of scientific payload is implemented in the international cooperation.

3. The following set of scientific instruments is determined:

4. The complex ECHO-EM for basic satellite is created in the following cooperation.

• Lviv Center of Space Research Institute (LC SRC), Ukraine.
  

• Space Research Institute of Russian Academy of Sciences (IKI), Russia (S.I. Klimov):
• Sheffield University, Great Britain (M. Balikhin);
• Laboratory of physics and chemistry of space (LPCE/CNES), Orlean, France (M. Parrot);
• Space Research Institute of Swedish Academy of Sciences (K. Stasiewicz);
• Danish meteorological institute (F. Primdal);

5. LC SRI (Ukraine) and Central Research Institute for Physics RMKI (Hungary) are responsible for designing of onboard data collecting system for SEM-subsatellite (the sharing of work is to be determined). LC SRI is the Principal Designer.

6. DB 'Yuzhnoe' and SRI (Ukraine) elaborate the problem of data timing for all three satellites with accuracy not worse than 1-5 microseconds.

7. US side pays attention that the subsatellite SAM should not have booms which may shade the antennas of TOPADS-device. The whole surface of a subsatellite SAM have to be covered with metal foil bonding (without slots). US side will consider the possibility to install in TOPADS-device the additional electronic card for measurements of ULF E-field fluctuations (0.1 - 20 000 Hz). The participation of US side in WARNING mission will be finally confirmed after NASA decision (not later than August, 1998).

8. The Institute of Atmospheric Physics of Czech Academy of Sciences will undertake all efforts

1. to elaborate, manufacture and test the following instruments:
   1. magnetic field two-channel spectral analyzer SAMW- 2;
   2. EUV photometers PHEU (in cooperation with Max-Plank Institute, Germany);
   3. Cold plasma probe CPM;
2. to prepare and deliver the necessary documentation to DB 'Yuzhnoe' and SRI;
3. to elaborate possibility of telemetric data reception at ground based station Panska Wes.

9. Central laboratory of solar-terrestrial connections of Bulgarian Academy of Sciences suggests:

1. to include into payload of basic satellite a package for thermal plasma measurements. The package consists of
   1. cylindrical Langmuir probe for measurement of electron density and temperature, ion density and satellite potential;
   2. braking potential analyzer for measurement of ion density, mass consistent and temperature;
   3. ion drift analyzer.
   The Bulgarian side is ready to cooperate with SDD "Diskret" (Ukraine) and IKI (Russia) in order to design the braking potential analyzer and ion drift analyzer.
2. in cooperation with Kiev University (Ukraine) to design photometers for optical block. Bulgarian side is responsible for manufacturing of electronics, composition and calibration of the instrument. Kiev University is responsible for the optics.
3. Bulgarian side participate in ground based optical observations in Stara Zagora. Bulgarian side will consider the possibility to engage Panagyurishta's magnetic observatory to participation in the experiment.

10. IZMIRAN asks scientific committee to consider a possibility to change the initial WARNING satellites orbit:

• to increase an inclination up to 82^o
• to raise an orbital altitude up to 800 - 900 km.

11. The final right of decisionmaking about the changing of payload composition belongs to the International Scientific Committee. The final decision is to be based on the scientific and technical proposals analyzing, Design Bureau 'Yuzhnoe' inference about the technical feasibility to carry out particular experiment.

12. The designers of instrumentation send their proposals to Design Bureau 'Yuzhnoe' (V.S.Gladilin) and to Space Research Institute (V.N. Ivchenko) up to May 11, 1998 accordingly to instructions of "GENERAL STANDARD SPECIFICATION ...", item 1.5.1a of section 1.5 "Volume of presented materials". The proposals obtained after May 11, 1998, will not be considered. SRI is responsible for collecting of all technical proposals and their preparation for consideration. The information is to be represented in WORD-6 format with future transition to PDF.

13. DB 'Yuzhnoe' studies the obtained proposals and informs International Scientific Committee about results of considiration till June 1, 1998.

14. Scientific committee considers the possibility to increase the number of ground based stations for receiving of TM information from satellites.

15. SRI has been asked to multiply the "Program" report for the usage of all mission participants.

16. Because of the necessity of high electromagnetic cleanness all spaceborn systems of WARNING complex (scientific and service as well) have to avoid processing in frequency range 0.1 - 20 000 Hz. The use of these frequencies in high-power sources should be eliminated. DB 'Yuzhnoe' is asked to submit to Principal Investigators the comparative characteristics of electromagnetic disturbances of two proposed versions of satellite orientation and stabilization system.

17. Prof. Bodo Raynish (Lowell university, USA) has been included to the International Scientific Committee.

18. The new version of the Memorandum of Mutual Understanding will be delivered to the participants after the decision of International Scientific Committee (June, 1998) for the final discussions before signing on the next meeting. The time and place of the next meeting will be determined. The participants are grateful to Bulgarian colleagues for the proposition to organize next WARNING meeting in Bulgaria.

19. The primary problems which have to be discussed during the following meeting are:

• Problems of a reception, processing and transmission of the information;
• The program of ground support;
• Evaluation of electromagnetic, plasma, gas-dynamic and illuminating conditions in the proximity of the satellites.
