health savings account (HSA) DEFINITION: A health savings account (HSA) is a tax-advantaged account where money can be set aside to pay for future medical expenses. HSAs can be offered as an employment benefit (money can be contributed by the employee and/or the employer) or they can be set up by someone who purchases individual health insurance. In order to contribute to an HSA, the account owner has to have an HSA-qualified high-deductible health plan in place. The IRS sets limits on the minimum and maximum out-of-pocket levels for the HDHP and also has contribution limits for HSAs.
Microsoft Space Simulator. Microsoft Space Simulator is a space flight simulator program, based on Microsoft Flight Simulator for MS-DOS. It was one of the first general-purpose space flight simulators and it incorporated concepts from astrodynamics and celestial mechanics. Lee Buchanan (November 1994).
Simulator benefits: With a constellation simulator, every time a test scenario is run, the signals produced are identical. The scenario will start at the same time on the same date, and the satellite positions will be identical â even down to the relative phase offsets between the different signals.
