Comments on Magnetic Field Gradients and Their Uses in the Study of the Earth's Magnetic Field by Harrison and Southam
Autor: C. D. Hardwick, J. Bradley Nelson, D. L. Marcotte
HARRISON and SOUTHAM (1991) point out the many benefits of magnetic gradiometry including the enhancement of short-wavelength (nearby) anomalies relative to long-wavelength (far away) anomalies, and the heavy attenuation of diurnal or magnetic storm

Automated Interpretation of Horizontal Magnetic Gradient Profile Data
Autor: J. B. Nelson, C. D. Hardwick, David L. Marcotte
A new technique has been developed to estimate the vertical magnetic gradient [Formula: see text] along a profile from measurements of the two orthogonal horizontal magnetic gradients [Formula: see text]. In addition, a means of identifying two‐dim

Characterization of Phase and Multipath Errors for an Aircraft GPS Antenna
Autor: C. D. Hardwick, Jeffrey Liu
In the application of GPS to airborne gravity measurements, the centimeter-level phase errors of an aircraft-mounted antenna can influence the results. Furthermore, the aircraft structure can give rise to multipath errors that are even more significa

An experimental voice command system for management of an integrated navigation system
Autor: M.E. Bower, D.L. Marcotte, C.S. Swail, J.E. Jordan, G. Hoftyzer, C. D. Hardwick
Publikováno v: [1992] Proceedings IEEE/AIAA 11th Digital Avionics Systems Conference.
An experimental voice command and integrated navigation system is described. The implementation is in a Convair 580 research aircraft. The system uses an interactive cockpit display to provide waypoint and routing management, fuel information, aircra

On: 'Important design considerations for inboard airborne magnetic gradiometers' by C. D. Hardwick (GEOPHYSICS, 49, 2004–2018, November 1984)
Autor: C. D. Hardwick, Peter Hood
Publikováno v: GEOPHYSICS. 51:192-193
In the above paper, the author states that military‐type magnetic compensators such as the nine‐term compensator produced by Canadian Aviation Electrons (CAE) of Montreal, Quebec may not be suitable for aeromagnetic survey work. In view of his do

The paper acknowledged that military‐type compensators have been used in geophysical exploration to produce useful vertical gradient maps. In fact, at NAE we flew a CAE nine‐term compensator (9‐TC), the type referred to by Dr. Hood, in a four
