[2] Explorer 14 was designed to study space physics, and so had a multitude of instruments including a cosmic-ray detector, a particle trapper, and a magnetometer.

Its instrumentation included 10 particle detection systems for the measurement of protons and electrons and their relation to magnetic fields, a solar cell damage experiment, optical aspect sensor and one transmitter.

During ground processing of the telemetered data, the analog information was digitized with an accuracy of 1/100 of full scale.

One analog channel was subcommutated in a 16-frame-long pattern and was used to telemeter spacecraft temperatures, power system voltages, currents, etc.

[5] This experiment was designed to detect and study the positive ion component of the solar plasma.

The instrument had a fan-shaped angular acceptance for positive ions of 10° by 80° (full width at half maximum).

[6] his experiment was designed to measure the directional fluxes and spectra of low-energy trapped and auroral protons and electrons.

The energy fluxes of electrons in three ranges were measured separately using scatter geometry, absorbers, and the phototube current.

The experiment used an array of three thin-windowed Anton type 213 directional Geiger-Müller counters.

The trapped particles experiment operated satisfactorily until 11 August 1963, when modulation of the telemetry signal ceased.

[8] The spacecraft functioned well except for the period from 10 to 24 January 1963, and after 11 August 1963, when the encoder malfunctioned terminating the transmission of usable data.
