![]() Space and Hardware Componentsĭeveloped by CNES, the MERLIN platform is an enhancement of a minisatellite from the Myriade platform series referred to as Myriade Evolutions. The satellite is designed to be compatible with a Local Time Ascending Node (LTAN) of 06 hours. MERLIN is set to undergo a near-polar sun-synchronous orbit of altitude 500 km, orbital period of 90 minutes and a repeat cycle of approximately 28 days. Featuring a 10 m accuracy of measurement for scattering surface elevation, MERLIN will also target a Relative Random Error (RRE) of less than 8 ppb and a Relative systematic error of less than 1 ppb. IPDA LIDAR onboard MERLIN will aim to provide global coverage, resolving total columns with a 50 km horizontal resolution. Specific scientific performance requirements include the ability to resolve large wetland fluxes, inter-hemisphere gradients, seasonal and annual methane gas budgets on a continental and country-scale and Kyoto protocol-like monitoring. IPDA LIDAR is set to have unprecedented accuracy and precision of spatial and temporal gradients of atmospheric methane gas columns to thus contribute to research into the causes of climate change. IPDA LIDAR will use the laser light of a wavelength at the centre of the methane absorption line scattered back from the Earth’s surface, in comparison with a reference beam, to determine the column content of methane gas in the atmosphere. Time tracking reports also have strategic benefits, as they can be useful in helping an organization perform budget analysis or identify discrepancies in compensation.MERLIN will carry a single instrument onboard, an Integrated Path Differential-Absorption Lidar (IPDA LIDAR). Generally, a manager will review employees’ timesheets for the pay period to verify that they are correct, at which point HR or the software will calculate the total hours worked along with any overtime hours.Īll time tracking involves some form of reporting, first and foremost as a way to submit approved and verified hours to payroll for processing. Approvals are essential for an organization to ensure accuracy and compliance in compensation. In both electronic and manual systems, the times of day recorded by the system are called timestamps, and the record of an employee’s timestamps is kept in a timesheet. ![]() Modern software-based systems use a unique identifier to clock an employee in and out time-tracking functions built into a point-of-sale system often use an employee’s first login and end-of-day logout as a way to perform time entry as well as grant system access. Time entry is often referred to as “clocking in and out” or “punching in and out,” the latter of which refers to “punching” the button on a physical time clock that stamps the time on a paper timecard. These times are called timestamps, and may be recorded on a physical document called a timecard or via an electronic method like a spreadsheet or time-tracking software. Time entry is the daily process by which an employer records employees’ starting times, finishing times, and any breaks not included in the employee’s contractual agreement. Now they are often handled by computer software designed specifically for that purpose however, there are still organizations who perform time tracking manually, either in part or in full. Originally, these functions were all performed entirely by hand. Time tracking breaks down into three main components: It is a subcategory of time and attendance, which is a broad term that typically encompasses time tracking as well as other elements like attendance, time off, billable hours, and scheduling. Time tracking refers to how organizations record the working hours of hourly employees and ensure those employees are compensated accurately for their time. ![]() What is Time Tracking?
