The Zardoz satellite does exist.
In May 1929, J. Galle and G. Talon made new successful research of the LDE phenomenon:
"... In May 1929, a French expedition was in Indo-China to study an eclipse of the Sun. J B Galle and G Talon, captain of the naval vessel L'Inconstant, had orders to study the effects of the eclipse on radio propagation, particularly long delayed echoes. They used a 500 watt transmitter with a 20 meter aerial attached to an 8 meter mast, powered by the generators of the Indo-China Hydrographic Service vessel La Perouse. The two aptly named ships sailed from Saigon on May 2nd, and on May 5th they conducted test transmissions in "la baie de Penitencier", PouloCondere, and detected long delayed echoes. Weather conditions prevented work on May 6th and 7th, but on the 8th the ships were back on station and transmitted for the first ten minutes of every half hour.
On May 9th, the day of the eclipse, signals were sent for nearly six hours with one 20 minute break, and again for ten minutes in every half hour the following day. Two dots were sent every 30 seconds on 25 metres wavelength, varying in a fixed musical sequences to aid correct identification and timing of the echoes. Large numbers of echoes were heard, clearly divided into two groups: weak echoes, about 1/100 the original signal strength, and strong ones 1/3 to 1/5 the intensity of the transmitted signal, with no significant relation between strength and delay time. (These intensities are too great for natural reflection at such apparent distances, but no-one seems to have thought of that at the time.)
In their preliminary report Galle and Talon said echoes stopped altogether during the totality of the eclipse, but in fact they paused 3 1/2 minutes before the eclipse became total and began again half way through it. Delay times ranged from 1 second to 30 seconds, though two 31 second echoes and of 32 seconds were heard between 15.40 and 16.00 on the day of the eclipse. 1 and 2 second echoes might seem impossible for a probe in the Moon's orbit, but for an extraordinary circumstance.
At 14h 19m 29s on the day of the eclipse the operator "forgot" to send the required dots, but 5 and 10 second echoes were heard nonetheless. From this Galle and Talon concluded that some echoes might have 40 seconds delay or more: either their musical tone sequences let them down, or they were unable to believe evidence that the probe was anticipating their signals as it transmitted its "replies".https://arxiv.org/ftp/arxiv/papers/1007/1007.4054.pdfOf course, N. Tesla's detection equipment was much more precise, in fact no other scientist has been able to duplicate it to the present time.
What Tesla was able to accomplish is to detect SCALAR SIGNALS, using his Teslascope machine: the very source for his extremely precise recording of the pulses.
Using the Teslascope, Tesla made this statement:
"The signals are too strong to have traveled the great distances from Mars to Earth," wrote Tesla.
"So I am forced to admit to myself that the sources must come from somewhere in nearby space or even the moon.This means that the Zardoz satellite is able to emit scalar waves.
We are getting signals from clouds one hundred miles away.
N. Tesla, 1899
The arrangement of my receiving apparatus and the character of the disturbances recorded precluded the possibility of their being of terrestrial origin, and I also eliminated the influence of the Sun, Moon, and Venus. As I announced, the signals consisted in a regular repetition of numbers.
N. Tesla, 1921
Tesla concluded that these signals, or this strange unnatural object they originate from, was indeed extraterrestrial.
At first he assumed they were originating from Mars.
Later he changed that opinion and stated in one of his new conferences that the signal was coming
from somewhere much closer in space."The signals are too strong to have traveled the great distances from Mars to Earth," wrote Tesla. "So I am forced to admit to myself that the sources must come from somewhere in nearby space or even the moon.

http://theunredacted.com/the-black-knight-satellite-sentinel-from-space/In December 1927, Carl Stoermer, the Norwegian Professor of Mathematics at University in Olso, and explorer of echo radio was contacted by two American scientists, Leo C. Young, radio engineer and Dr. A. Hoyt Taylor, chief consultant of electronics at the naval research laboratory. During their experiments with radio waves, Young and Taylor observed unnatural signals coming from space.
By December 1928, a number of scientists were interested – Jurgen Hals of Phillips Einddhoven laboratories in Holland had discussed his findings with Professor Carl Stormer of Oslo, mentioning three-second delays he had experienced with an experimental radio transmitter. After another year, on October 28 1929, Dr Van der Pol, also of Phillips, confirmed that he had noted further odd echoes from a planned emission of impulses at the same time every morning. It was van der Pol’s analysis of the delay between emissions and the reciept of their echoes, always on the same wavelength, that effectively excluded ideas that they may have been bouncing off the Moon, or inner Van Allen belt, or that they might have been somehow stored and reflected from layers of ionised gas.
