Pat Delgado in 2008.

In 1961 I transferred from the Woomera Missile Range to DSIF 41 and was there until 1966.

During that time I operated and maintained equipment in the servo section of the dish.

The work called for a great variety of shift times, sometimes extending up to 28 hours non-stop if there was an equipment or a dish drive crisis. It was a case of becoming thoroughly familiar with every part of the system I was responsible for. Any malfunction of the system when tracking a spacecraft called for almost instantaneous recognition and correction of the fault. Any loss of tracking time was considered a disaster. You should have seen me going up those dish ladders sometimes. I considered sliding down the ladder handrails for quickness but the joins in them would make your eyes water!

On some lengthy tracking sessions meals were supplied in the HQ building and it was an in-joke at the time that some of the operations teams were gaining a yellow pallor through devouring such huge quantities of scrambled eggs!

There was a short period when I was transferred to Minitrack while parts of the dish system were being serviced. I operated the tracking equipment there and the large Baker Nunn camera. The most difficult part of the latter was developing the films in total darkness doing everything by feel.

Strangely, after I left Island Lagoon and tracking spacecraft, my next job was installing and testing analytical instruments in Polaris nuclear submarines under the Atlantic.

I will never forget the time I spent at Island Lagoon. It was the early years of space exploration and working on such state of the art equipment and being on the leading edge of space technology created a great team spirit and was both exciting and very rewarding.

Not long before he left Island Lagoon, Pat received a personal reference from Minitrack’s Station Director Eric Hird.

While Pat would doubtless be embarrassed by the glowing description, this refeernce also gives a feel for space tracking at Woomera in the mid-1960s, and for that reason we include it here:

“I have been very well acquainted with Mr Pat Delgado since April 1962 upon his appointment to the Deep Space Station at Woomera, South Australia, as a Technical Officer in the Servo section.

Work at the tracking station is always exacting, the more so, because the occasional lulls in activity lure the inexperienced and unsuspecting individual into a state of false security. The long hours during a mission soon shave a man down to his basic individuality and when the going is hard and the level head of a well-trained, responsive person is required, Pat Delgado is a very good man to have around. He has a pleasing disposition, a keen sense of humor, a ready wit that is never inappropriate and a high sense of duty. He has always been very popular with those around him, both on and off the job. He has a considerable manual dexterity which, coupled with his unruffled calm, has frequently won him some difficult tasks which have had to be performed under heavy pressure. He is hardworking and has an unimpeachable character.

His duties at Woomera Station primarily concerned the effective running of the hydraulic-electric servo system of an an 85-ft. diameter HA-DEC radio-antenna. The motive power was a 5000# oil system which required a lot of close and careful maintenance upon the motors valves, and delivery pipes. Some of the work entailed climbing the antenna structure to carry out inspections etc., often at night or in blistering heat and occasionally sandstorms. The control signals for the third-order closed-loop control system were derived from the S-band receiver and required careful interface liaison during countdowns. Furthermore, the electronic controls required meticulous adjustment which can only come from knowledgeable experience, in order to achieve the optimum response.

During the highly important first-pass on all new missions he was personally responsible for acquiring the spacecraft signal in conjunction with the receiver staff. This was always a moment of high tension and the success of the action rested absolutely on these men. Pat Delgado was never known to fail.

During the past five years, Pat Delgado's long-time experience of tracking station work has led him into numerous other areas of activity also. He has successfully worked as a Receiver operator and also in the Tracking and Data Handling System and the Telemetry and Command System.

For many months he worked at the Satellite Tracking Facity [i.e. Minitrack] at Woomera during an operational lull at the Deep Space Station. He was faced with learning very quickly an entirely new mode of operation. The station was taking about 35 telemetry passes a day of up to a dozen orbiting spacecraft, each one of which required different equipment set-ups to enable telemetry data to be obtained. Fast, accurate technical work was needed as well as the completion of considerable documentation. He also learned how to operate the Minitrack system which is a radio-interferometer device used to determine the precise moment of latitudinal- or longitudinal-passage of a radiating spacecraft.

At this time Pat Delgado is a permanent Technical Officer, Grade 2 in the service of the Commonwealth Department of Supply. This is a senior position and he is worthy of it.”
