Also called:
International Satellite for
Ionospheric Studies
Memorandum of Understanding
(MOU)
between NASA and the Canadian Defense
Research Board and the Canadian Dept. of Communications,
1963
Date of launch (range):
Jan 30, 1969 (WTR)
Launch vehicle:
Delta Standard Vehicle 3E
Shape:
oblate spheroid (8-sided)
Weight (kg):
236
Dimensions (m):
1.27, diam.
1.07, height
Power source:
solar cells plus 3 NiCd
batteries
Prime contractor:
CA Victor Co., Montreal
Date of reentry:
N/A
NASA's role:
launch vehicle, technical support,
tracking and data acquisition; participation in experimental
program
Responsible NASA center:
GSFC
Project manager:
Evart D. Nelson
Project scientist:
John E. Jackson
Objectives:
To continue to extend a joint
U.S.-Canadian program of ionospheric studies by combining
sounder data with correlative direct measurements for a time
sufficient to cover latitudinal and diurnal variations
during a period of high solar activity.
Experiments (responsible country or
organization):
.
swept frequency sounder (Defense
Research Telecommunications Establishment)
fixed frequency sounder (DRTE)
VLF receiver/exciter (DRTE)
radio beacon (Univ. of Western
Ontario)
cosmic radio noise (DRTE)
energetic particle detector (National
Research Council, Canada)
ion mass spectrometer (Air Force
Cambridge Research Laboratories, U.S.)
cylindrical electrostatic probe
(GSFC)
spherical electrostatic analyzer
(AFCRL)
Results:
Successful; ISIS 1 gave experimenters
an opportunity to combine on one satellite direct and
indirect measurements of important ionospheric parameters.
Data were obtained until Oct. 1979; ISIS 1 was the third in
a series of 5 joint experiments with Canada.
