The company's Falcon 9 rocket will launch from Vandenberg Air Force Base in Southern California.
The private commercial space company announced the findings last week of its investigation into the explosion.
"With completion of the static fire test, our first launch has just gotten that much closer", said Matt Desch, chief executive officer at Iridium. The "static fire" test culminated in the ignition of the first stage's nine Merlin 1D engines for a few seconds, briefly ramping up to full power with 1.7 million pounds of thrust.
CEO Elon Musk tweeted that all systems were go for the scheduled Sunday launch, but the Federal Aviation Administration had not yet issued a license for the launch.
On Jan. 2, SpaceX announced that, after a thorough investigation that spanned four months, and with help from the FAA, the National Transportation Safety Board (NTSB), the National Aeronautics and Space Administration (NASA) and several experts, the company may have finally found the cause of the explosion in September.
Should this launch prove successful, SpaceX is set to send 70 more satellites into space for Iridium in the months to come.

In a country of mandatory military service, the ten-month long trial over the baby-faced Azaria has roiled the country. Prosecutors had argued that al-Sharif "represented no immediate threat for the accused or others who were present".
The company told regulators t hat it would reconfigure the helium tanks used in the Falcon 9 rocket and load the liquid gas at a warmer temperature.
SpaceX's Falcon 9 rocket will launch with 10 Iridium NEXT satellites. SpaceX said recovered helium tanks - called composite overwrapped pressure vessels, or COPVs - at the launch pad showed buckles in their liners. But the FAA still has to review the investigation report and issue a license to SpaceX before the launch. SpaceX applied for a license to launch the Iridium NEXT satellites from Vandenberg Air Force Base.
In response to the failure, SpaceX said it plans to change the design of its pressure vessels.
The satellite swap, where 66 new satellites will replace old ones now in orbit, is the largest and most complex of its kind.
According to official statement given from Iridium, mission will be postponed for at least 6 days with first possible date at 14th January 2017 at 17:43 UTC. That number includes the 66 operational spacecraft needed to update the Iridium network, plus spares.
