1. Introduction
NASDA developed space and ground segments of Marine
Observation Satellite-1 (MOS-1) observation system and succeeded
in launching the MOS-1 from Tanegashima Space Center by N-
Kiroeket.ato40223.JS8T.(1:223.UTJ..0n 5E£eb4. 19,1987. .Tháis:was
launched into specified sun-synchronus orbit and called "Momo
(Peach) 1". The MOS-1 carries 4 mission instruments (1)Multi-
Spectral Electronic Self Scanning Radiometer(MESSR)(2)Visible and
Thermal Infrared Radiomater (VTIR) (3)Microwave Scanning
Radiometer (MSR) and (H)Data Collection System Transponder
(DCST). It was confirmed that all mission instruments are very
good during mission check period (three months after the launch)
though DCS suffered from harmful radio interference due to outer
Source which was eliminated by changing the center frequency of
Data Collection Platform (DCP).
In order to evaluate MOS-1 total observation system,NASDA
planned and initiated MOS-1 Verification Program (MVP) since
March,1987. NASDA is conducting MVP in collaboration with joint
research organizations, domestic and foreign organizations. As a
part of MVP, NASDA conducted airborne experiments on MOS-1
passing days in 1987-1988.
In this paper, the outline of MVP will be described and the
some initial results of MVP will be presented.
2. The outline of MVP
Main mission objectives of MOS-1 are to establish fundamental
earth observation technology and to observe ocean, land and
atmosphere by using three radiometers (MESSR,VTIR,MSR) covering
visible,near-infrared,thermal infrared and microwave wavelengths.
In order to achieve these mission objectives and to evaluate
MOS-1 observation system, NASDA conducted field experiments by
using MSR breadbord model (BBM) on the ground, tower and others
in 1981-1983, airborne verification experiments by using
MOS-1 sensor engineering model(EM) mounted on an aircraft in
1984-1985 Based upon these experiments NASDA planned MOS-1
Verification Program. The content of the MVP is shown as
follows.
2.1 Purpose of MVP
Purpose of the MVP is as follows:
(1) Evaluation of geometoric and radiometoric distortion
compensation accuracy
(2) Evaluation of performance of MOS-1 observation system
(3) Evaluation of effectiveness of MOS-1 observation parameter
from various fields of remote sensing
(4)Reflection of the above results in the development and
operation of advanced earth observation system in the future
2.2 Methodology of MVP
In order to evaluate MOS-1 observation system, MOS-1 data,
airborne data, truth data,other earth observation satelite data
are required in the framework of the MVP. :
